bool OEMDLSetParity(OEMolBase &mol, bool value)

Sets the MDL ‘chiral’ flag status for a molecule to the passed value. Setting the value to true implies setting the chiral flag ‘on’ and indicates absolute stereochemistry for any marked stereocenters. OEMDLHasParity will return true after setting a value via this function, and OEMDLGetParity will return the value. OEMDLClearParity will clear the property from the molecule.
