Check Digit Verification of cas no

The CAS Registry Mumber 324521-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,4,5,2 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 324521-72:
(8*3)+(7*2)+(6*4)+(5*5)+(4*2)+(3*1)+(2*7)+(1*2)=114
114 % 10 = 4
So 324521-72-4 is a valid CAS Registry Number.

Synthesis of 4-arylaminoquinazolines and 2-aryl-4-arylaminoquinazolines from 2-aminobenzonitrile, anilines and formic acid or benzaldehydes

Szczepankiewicz, Wojciech,Suwiński, Jerzy,Bujok, Robert

, p. 9343 - 9349 (2007/10/03)

2-Aminobenzonitrile treated with anilines in the presence of aluminium chloride gave respective 2-amino-N-arylbenzamidines. 4-Arylaminoquinazolines lacking a substituent at the 2 position were obtained directly by heating 2-amino-N-arylbenzamidines in formic acid; in similar conditions other carboxylic acids did not react with the amidines. The latter when treated with aldehydes afforded 2-aryl-4-arylimino-1H-2,3-dihydroquinazolines readily oxidizable by potassium permanganate to 2-aryl-4-arylaminoquinazolines.
