Check Digit Verification of cas no

The CAS Registry Mumber 498553-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,8,5,5 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 498553-39:
(8*4)+(7*9)+(6*8)+(5*5)+(4*5)+(3*3)+(2*3)+(1*9)=212
212 % 10 = 2
So 498553-39-2 is a valid CAS Registry Number.

Synthesis of substituted pyrroles in the glaser reaction

Vizer,Yerzhanov,Dembitsky

, p. 66 - 73 (2006)

The substituted pyrroles and dipyrroles along with diacetylenes and cumulenes have been synthesized in high yields using a new synthetic method under mild reaction conditions using the Glaser coupling reaction. Although diacetylenes are formed from 2-prop
