Hi Sergio,

there may be random entries in the Resolver database behind 
http://cactus.nci.nih.gov/chemical/structure but definitely
nothing systematic.

Thanks Greg,

I agree, it certainly works for molecules, however I am testing whether cactus is able to provide names to molecular fragments as well. Things like methyl phosphinite (COP) are named after that. 

See:

Do you have any hints on systematically naming molecular fragments?

molcovert does not generate a name either.

That's not actually a stable molecule. it is, at best, a piece of a molecule. OC(N)N works fine with the NCI lookup.
What molecule are you trying to name?
