Check Digit Verification of cas no
The CAS Registry Mumber 19649-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,4 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19649-50:
(7*1)+(6*9)+(5*6)+(4*4)+(3*9)+(2*5)+(1*0)=144
144 % 10 = 4
So 19649-50-4 is a valid CAS Registry Number.

Boldyrev, B. G.,Grivnak, L. M.
, p. 324 - 330 (2007/10/02)
Arylazoarenethiosulfonates were obtained, and their structures and chemical characteristics were studied.It was shown that arylazoarenethiosulfonates have a nonionic structure, and this explains their high stability.It was established that they enter with difficulty into reactions with the release of nitrogen, but they enter readily into azo-coupling and reduction reactions.
KINETICS AND MECHANISM OF THE AZO COUPLING REACTION OF 1-AMINONAPHTHALENE-4-SULFONIC ACID
Demian, Barbu A.,Exner, Otto,Sallo, Aurora
, p. 748 - 754 (2007/10/02)
Kinetics of the azo coupling reaction of 1-aminonaphthalene-4-sulfonic acid with nine substituted benzenediazonium chlorides was investigated at four temperatures.The results were processed in terms of the isokinetic relationship and of an isoparametric relationship with temperature and ? constant as independent variables.There is a great similarity to the coupling reaction of 1-hydroxynaphthalene-4-sulfonic acid; all the results are consistent with a cyclic transition state implying variable association of a water molecule.
