Currently ISBN-13s which do not start with '978' or '979' display an "Invalid ISBN checksum" message on Publication pages. It should be changed to "Bad format", the same message that is displayed for non-numeric ISBN values and values that are not 10 or 13 characters long.
Conversely, submission review pages currently display an "Invalid ISBN format" yellow warning for properly formatted ISBNs with a back checksum. The yellow warning should be changed to "Bad Checksum".
