CID AKA Chemical IDentifier from pubchem. Currently only 19,157,505 entries but give it time.
Right. And it is gonna take a bit more time. I've noticed they have real problems with uniqueness -- for example, it's hard to say whether thimerosal (CAS 54-64-8) is Pubchem sid 5908, 67361, or 16682923. (I think I found several other examples, back when I was attempting to correlate the two.)
