No. That requires look up, so only works against an existing database.
Chemspider is doing this, but is not a general solution. InChIKey's
are not unique, though clashes rare, and not observed so far.

Indeed. However, InChIKey is less precise. RDF allowing us to be do
things in an exact manner, I rather use InChI.

But can never be used for owl:sameAs like relations.

That was precisely the reason why I started the service.
