The Chemistry Development Kit (CDK) is a scientific, LGPL-ed library for bio- and cheminformatics and computational chemistry written in Java.
The main home page of the CDK is now at: http://cdk.github.io
PTE-1.5 is for Mathematica 11.1 (not mm14 - needs ver change fixing)
PTE-1.4 and prev for Mathematica 4.0 linux
PTE generates periodic tables from variable data (the data and layout can be changed for a particular subject). Includes Pauli Exclusion makers and some data. Charts can be browsed with an iPhone nicely (may need .jpg, .gif nicer). It's printable at a small size. Layout change un-restricted but is non-interactive. which is good and bad: it does the job.

Libraries and scripts for molecular modelling written in Perl
A perl molecular toolkit designed to assist in general molecular modelling activities. Silico provides file format conversion, molecular manipulation and analysis and a simple way to write wrapper scripts around other preexisting software packages.
A library to easily analyse output of the Heidelberg MCTDH code
This project aims to provide a set of routines to easily read in and manipulate the output of the Heidelberg MCTDH code.
The goal is to enable a new user to quickly get started with writing custom analysis programs. Also, it should enable more experienced users (== us) to write small, clean, and testable analysis programs, something that seems incompatible with the Fortran-77 code of the Heidelberg MCTDH package.
With up to 25k MAUs and unlimited Okta connections, our Free Plan lets you focus on what you do best—building great apps.
You asked, we delivered! Auth0 is excited to expand our Free and Paid plans to include more options so you can focus on building, deploying, and scaling applications without having to worry about your security. Auth0 now, thank yourself later.
Open Babel is a chemical toolbox designed to speak the many languages of chemical data. It's an open, collaborative project allowing anyone to search, convert, analyze, or store data from molecular modeling, chemistry, biochemistry, or related areas
Balance chemical reaction and compute material balance
This Python program is used to balance a chemical reaction and to compute the material balance.
Furthermore, it's able to check molecules and to write the condensed strutural formula from the name of an organic molecule. (Those both functionalities are still limited.)
ASCEND is a modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provid
An editor for small organic molecules, written in C using gtk+. It can read and write SMILES and cml and can save to dia's file format. It is suitable for creating chemical molecule diagrams for lower level chemistry/ochem lab reports.
Secure File Transfer for Windows with Cerberus by Redwood
Protect and share files over FTP/S, SFTP, HTTPS and SCP with the #1 rated Windows file transfer server.
Cerberus supports unlimited users and connections on a single IP, with built-in encryption, 2FA, and a browser-based web client — all deployable in under 15 minutes with a 25-day free trial.
PerlMol is a collection of Perl modules for chemoinformatics and computational chemistry with the philosophy that "simple things should be simple". It should be possible to write one-liners that use this toolkit to do meaningful "molecular munging".
CDL provides a generic C++ framework to write algorithms for the calculation of molecular descriptors. CDL provides efficient substructure search, fingerprints and pharmacophore algorithms, and many more for the calculation molecular descriptors.
