#31 CAS Number Search/List

[mptsang]

I'd like to suggest that openLCA be able to search the processes, flows, etc via a CAS Number, and also so that substances can be sorted in list by the CAS Number as well. I think that identifying CAS Numbers will make the process of identifying a substance flow/process much easier. Many chemicals unfortunately have multiple common names, and openLCA seems to be case and space sensitive to substance names.
