112331-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112331-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,3,3 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 112331-34:
(8*1)+(7*1)+(6*2)+(5*3)+(4*3)+(3*1)+(2*3)+(1*4)=67
67 % 10 = 7
So 112331-34-7 is a valid CAS Registry Number.

Synthesis of Heterocycles via Nitrilium Salts; XVI. Pyrazolopyrimidines
Madronero, Ramon,Vega, Salvador
, p. 628 - 630 (2007/10/02)
Based on the electrophilic properties of nitrilium salts formed by interaction of 5-aroylaminopyrazoles, nitriles, and Lewis acids, a new general method for the synthesis of pyrazolopyrimidines has been developed.
