Check Digit Verification of cas no

The CAS Registry Mumber 1173095-67-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,0,9 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1173095-67:
(9*1)+(8*1)+(7*7)+(6*3)+(5*0)+(4*9)+(3*5)+(2*6)+(1*7)=154
154 % 10 = 4
So 1173095-67-4 is a valid CAS Registry Number.

Conversion of coumarins accompanied by opening and recyclization of the lactone ring. 1. Study of the reaction of 3-ethoxycarbonyl(3-acyl)coumarins with cyanoacetylhydrazine and its derivatives

, p. 1454 - 1465 (2007/10/03)

A stepwise sequence for the interaction of 3-ethoxycarbonyl(acyl)coumarins with cyanoacetylhydrazine, its N-acetyl and N-isopropylidene derivatives, leading to the formation of 3-cyanocoumarins, is proposed and demonstrated. It was established that the 3-cyanocoumarins formed are also able to participate in further conversions by a type of Michael reaction.
