Check Digit Verification of cas no

The CAS Registry Mumber 123081-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,8 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123081-52:
(8*1)+(7*2)+(6*3)+(5*0)+(4*8)+(3*1)+(2*5)+(1*2)=87
87 % 10 = 7
So 123081-52-7 is a valid CAS Registry Number.

Janietz, Dietmar,Rudorf, Wolf-Dieter

, p. 1661 - 1666 (2007/10/02)

2-Alkynyloxy-benzaldehydes 1 are obtained by alkylation of the corresponding salicylaldehydes either with p-toluenesulfonic acid propargylester or 1-acetoxy-4-chloro-but-2-yne.The aldehydes 1 are converted into the hydrazones 2 by reaction with p-toluenes
