Check Digit Verification of cas no

The CAS Registry Mumber 4719-41-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,1 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4719-41:
(6*4)+(5*7)+(4*1)+(3*9)+(2*4)+(1*1)=99
99 % 10 = 9
So 4719-41-9 is a valid CAS Registry Number.

Investigation of Reactions of Pyrazolin-Azomethin Dyes with 2-Pyrazolin-5-one

Gaca, J.,Kozlowski, K.,Trzcinska, M.,Kucybala, Z.

, p. 149 - 155 (2007/10/02)

The pyrazolin-azomethin dyes (3a-d) from 1-phenyl-3-methyl-2-pyrazolin-5-one and various photographic developers have been obtained.The reactions of decolourization of dyes during the 3-methyl-1-phenyl-2-pyrazolin-5-one action was investigated.We ascertained that the substituent changes in the developer had not only the influence on decolourization rate but they also had influence on the order change of the reaction.The various solvents had the same influence on the reaction rate of decolourization.
