Full Title

Full titles differ between systems:

IPC:

Compounds containing elements of Groups 5 or 15 of the Periodic Table > Phosphorus compounds > Heterocyclic compounds, e.g. containing phosphorus as a ring hetero atom > having nitrogen and oxygen atoms as the only ring hetero atoms

CPC:

Compounds containing elements of Groups 5 or 15 of the Periodic Table > Phosphorus compounds (sugar phosphates C07H11/04; nucleotides C07H19/00, C07H21/00; nucleic acids C07H21/00) > Heterocyclic compounds, e.g. containing phosphorus as a ring hetero atom > having nitrogen and oxygen atoms as the only ring hetero atoms

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1990.
