WebOct 8, 2015 · Longer term it would be better to grab the structures from the record e.g. using the SMILES or InChI, not the mol files, as both are required fields. Challenge for the future: dealing with generic structures – these won’t have InChIs/InChIKeys yet, but can be displayed via mol files (just the current renderer doesn’t deal with them).

InChIKey is a fixed-length format directly derived from InChI. It is based on a strong hash (SHA-256 algorithm) of an InChI string. Because of the hash nature of the InChIKey, there is no guarantee that two distinct molecules will have different InChIKeys. how many people work at innerslothWebThis is exemplified below by standard InChIKeys as well as standard InChI strings for neutral, zwitterionic, anionic and cationic states of glycine (note that neutral and zwitterionic states do not differ in the total number of protons so they have the same standard InChI/InChIKey): 13.3.
