CHEMO notation is a high-level line notation faithfully in line
with the IUPAC nomenclature to describe
organic compounds and even reactions. It has conserved the
concepts in nomenclature concerned with
superatoms (parent rings and functional groups) as well as
stereochemistry, by describing the corresponding
symbols and modifiers as universal descriptors that may be used in
estimation in chemistry. It can describe
fusion, atom replacement, configuration, etc. One can convert a
CHEMO formula or equation both to a
connection table composed of superatoms as nodes and stereo modifier
symbols and to a conventional one
composed of single atoms and vice versa. CHEMO notation describes
compounds more precisely than
prevailing line notations that denote only skeletal connection in them.
It does not request rigorous rules,
but a subsystem CANON can prepare unique representation from
it.
