OEMolToInChI

std::string OEMolToInChI(const OEMolBase &mol)

Creates a nonstandard round-trip form of InChI from a molecule. This function suppresses most of the normalizations done for the standard InChI to allow its use for round-trip activities.

Note

The underlying InChI code is v1.05 released on January 27, 2017.
