Check Digit Verification of cas no

The CAS Registry Mumber 117416-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,4,1 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117416-72:
(8*1)+(7*1)+(6*7)+(5*4)+(4*1)+(3*6)+(2*7)+(1*2)=115
115 % 10 = 5
So 117416-72-5 is a valid CAS Registry Number.

An Observation on Carboxylation of 4H-Cyclopentaphenanthrene

Minabe, Masahiro,Isozumi, Keisuke,Kawai, Ken-ichi,Yoshida, Masaaki

, p. 2063 - 2066 (2007/10/02)

Photocarboxylation of 4H-cyclopentaphenanthrene by carbon dioxide in the presence of N,N-dimethylaniline in dimethyl sulfoxide afforded 8,9-dihydro-4H-cyclopentaphenanthrene-8- and 2-carboxyl acid, and 4H-cyclopentaphenanthrene-8-carboxylic acid.These acids were derived into methyl-4H-cyclopentaphenanthrenes.
