Check Digit Verification of cas no

The CAS Registry Mumber 131929-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,2 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131929-20:
(8*1)+(7*3)+(6*1)+(5*9)+(4*2)+(3*9)+(2*2)+(1*0)=119
119 % 10 = 9
So 131929-20-9 is a valid CAS Registry Number.

N,N'-DIARYLDICHLOROMALONIMIDOYL CHLORIDES AND THEIR TRANSFORMATIONS

Shivanyuk, A. F.,Dashkovskaya, E. V.,Rozhenko, A. B.,Lozinskii, M. O.,Onishchuk, N. P.,et al.

, p. 1408 - 1416 (2007/10/02)

The hydrolysis and alcoholysis of N,N'-diaryldichloromalonimidoyl chlorides and their reactions with sodium azide in DMFA, with hydrazine hydrate and with triphenylphosphine lead to N,N'-diaryldichloromalonamides, imidic esters, bis(1-aryl-1,2,3,4-tetrazol-5-yl)iminomethanes, 3,5-diarylamino-4-chloropyrazoles, and 4-arylamino-3-chloro-2-quinolyltriphenylphosphomium chlorides.Depending on the nature of the nucleophilic agent, the N,N'-diaryldichloromalonimidoyl chlorides react either at the imidoyl chloride group N=C(Cl) (hydrolysis, alcoholysis) or at the two reactioncenters N=C(Cl)CCl2 (the reactions with hydrazine hydrate and triphenylphosphine).
