Check Digit Verification of cas no

The CAS Registry Mumber 220167-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,1,6 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 220167-91:
(8*2)+(7*2)+(6*0)+(5*1)+(4*6)+(3*7)+(2*9)+(1*1)=99
99 % 10 = 9
So 220167-91-9 is a valid CAS Registry Number.

Mixed cyclic trimers of porphyrins and dioxoporphyrins: Geometry vs. electronics in ligand recognition

Clyde-Watson, Zoee,Bampos, Nick,Sanders, Jeremy K. M.

, p. 1135 - 1138 (1998)

A series of metalloporphyrin-containing cyclic hosts has been prepared, which are electronically and geometrically programmed to recognize guests in a particular configuration. Electronic control is achieved by substituting the C-H meso positions with carbonyl groups, while geometric control is possible in the choice of the length of the rigid acetylene porphyrin linkers.
