Thanx. > Do you also provide InChIKey resolution? No. That requires look up, so only works against an existing database. Chemspider is doing this, but is not a general solution.

Indeed. However, InChIKey is less precise. RDF allowing us to be do things in an exact manner, I rather use InChI. > InChiKey's might be better for general use in RDF because they have a > guaranteed identifier length and therefore won't become cumbersome for > complex molecules.

That was precisely the reason why I started the service. Egon -- Post-doc @ Uppsala University http://chem-bla-ics.blogspot.com/
