Inchikey
The condensed, 27 character InChIKey is a hashed version of the full InChI (using the SHA-256 algorithm), designed to allow for easy web searches of chemical compounds. The standard InChIKey is the hashed counterpart of standard InChI. Most chemical structures on the Web up to 2007 have been represented as GIF files, which are not searchable for chemical content.

The molecular weight of a molecule is the mass of one molecule of the compound, and it is typically expressed in units of grams per mole (g/mol).
http://inchi.info/keygenerator_en.html WebAs reported variously last month (see here for one such review) IUPAC have now released a new (1.02beta) version of their software which allows hashed versions (fixed length 25-character) of the InChI, so-called InChIKey’s, to be generated which are much more search engine friendly.

CML is supported by several chemical programs, but is far less common than Molfile. For every molecule only one InChIKey is valid, however two molecules may have the same InChIKey – more details here. InChIKey is fixed length (27 characters).
