Check Digit Verification of cas no

The CAS Registry Mumber 135685-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,8 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135685-20:
(8*1)+(7*3)+(6*5)+(5*6)+(4*8)+(3*5)+(2*2)+(1*0)=140
140 % 10 = 0
So 135685-20-0 is a valid CAS Registry Number.

Inoue, Mitsunori,Ikeda, Chusaku,Kawata, Yuji,Venkatraman, Sundararaman,Furukawa, Ko,Osuka, Atsuhiro

, p. 2306 - 2309 (2008/03/12)

(Figure Presented) Bowled over: Calix[3]dipyrrins were synthesized from pyrrole and aryl aldehyde precursors by the Lindsey protocol, modified by the presence of a small amount of water. These bowl-shaped macrocycles can accommodate three metal (M) ions such as NiII and CuII in a hexagonal M3O3 manner (see structure; Cu green, N blue, O red, C black).
