77 Elemental Sequence for Ring System (/ES)

78 Elemental Sequence This kind of search retrieves rings or ring systems, not only on the basis of their element composition, but also of the element positions in ring(s). So it is equivalent at searching, by structure, a specific ring, or ring system, with any kind of bonds in the ring(s).

79 /ES  It is based on the sequence of atoms in the SSSR’s rings  For rings with only one element ES=EA  For each ring start with lowest alphabetical atom (not C)  Go to the next heteroatom (if any) in alphabetical order, by means of the shortest path  If the size is the same, rings with less C came first  Duplicate are neither removed nor compressed Elemental Sequence
