Full Title
Full titles differ between systems:
Derivatives of carbonic acid containing functional groups covered by groups in which at least one nitrogen atom of these functional groups is further bound to another nitrogen atom not being part of a nitro or nitroso group > Compounds containing any of the groups e.g. semicarbazides > the other nitrogen atom being further doubly-bound to a carbon atom, e.g. semicarbazones > the carbon atom being part of a ring other than a six-membered aromatic ring
Derivatives of carbonic acid containing functional groups covered by groups C07C269/00 - C07C279/00 in which at least one nitrogen atom of these functional groups is further bound to another nitrogen atom not being part of a nitro or nitroso group > Compounds containing any of the groups [IMAGE cpc-sch-C07C-0973.gif], e.g. semicarbazides > the other nitrogen atom being further doubly-bound to a carbon atom, e.g. semicarbazones > the carbon atom being part of a ring other than a six-membered aromatic ring
