Check Digit Verification of cas no
The CAS Registry Mumber 131213-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,1 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131213-35:
(8*1)+(7*3)+(6*1)+(5*2)+(4*1)+(3*3)+(2*3)+(1*5)=69
69 % 10 = 9
So 131213-35-9 is a valid CAS Registry Number.

Reaction of Pyrroloimidazole Mesomeric Betaines with Diphenylcyclopropenone Derivatives
Musicki, Branislav
, p. 110 - 118 (2007/10/02)
The cycloaddition reactions of title mesomeric betaines to diphenylcyclopropenone and diphenylcyclopropenethione have been studied.Cycloadditions lead to either 2(1H)-pyridone, 2(1H)-pyridinethione, or bicyclohex-3-en-2-one derivatives.Formation of
