# OEMDLHasParity¶

bool OEMDLHasParity(const OEMolBase &mol)
bool OEMDLHasParity(const OEMCMolBase &mol)


Checks for the availability of the MDL ‘chiral’ flag for a molecule. After reading from an MDL connection table this value is true, and false if the molecule did not originate from an MDL file or if the ‘chiral’ flag has been cleared. Calling the OEMDLGetParity function will return the actual on/off value of the ‘chiral’ flag from the MDL file header. After calling the OEMDLClearParity this function will return false.

The OEMCMolBase overload of this function checks the ‘chiral’ flag availability for the active conformer in the multi-conformer molecule.
