Check Digit Verification of cas no

The CAS Registry Mumber 1478440-47-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,7,8,4,4 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1478440-47:
(9*1)+(8*4)+(7*7)+(6*8)+(5*4)+(4*4)+(3*0)+(2*4)+(1*7)=189
189 % 10 = 9
So 1478440-47-9 is a valid CAS Registry Number.

Synthesis of aroylguanidines by an unexpected demethylation-addition cascade

Gu, Ling Hui,Guo, Zhen,He, Ling,Qi, Qing Rong

, p. 2533 - 2544 (2013/09/24)

A simple and efficient method was developed for the synthesis of N-aroyl-N′-arylguanidines under mild conditions by an unexpected demethylation-addition cascade reaction of readily available N-cyanoimidates with aryl amines. Moreover, 1-aryl-2-aminoquinazolin-4(1H)-ones and 2-(arylamino)quinazolin-4(3H)-ones can also be prepared by selective cyclization reactions of (2-fluorobenzoyl)- or (2-nitrobenzoyl)guanidines, respectively. This method provided two attractive strategies for the preparation 2-aminoquinazolinones derivatives from inexpensive reactants.
