Check Digit Verification of cas no

The CAS Registry Mumber 267002-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,7,0,0 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 267002-83:
(8*2)+(7*6)+(6*7)+(5*0)+(4*0)+(3*2)+(2*8)+(1*3)=125
125 % 10 = 5
So 267002-83-5 is a valid CAS Registry Number.

Synthesis of C - C-Bridged Bis-Isoflavones

Al-Maharik, Nawaf I.,Kaltia, Seppo A. A.,Mutikainen, Ilpo,Waehaelae, Kristiina

, p. 2305 - 2308 (2007/10/03)

Unique C - C-bridged bis-isoflavones 5, 8, and 9 were obtained by reaction of 2-bromomethyl-7,4′-dimethoxyisoflavone 4 with ethyl cyanoacetate anion or tetraethylammonium cyanide or by Pd-catalyzed ethoxycarbonylation, respectively. The phenolic carboxylic acid 7 is available from 5 in two steps.
