Check Digit Verification of cas no

The CAS Registry Mumber 5869-59-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,6 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5869-59:
(6*5)+(5*8)+(4*6)+(3*9)+(2*5)+(1*9)=140
140 % 10 = 0
So 5869-59-0 is a valid CAS Registry Number.

Synthesis of 5-(substituted phenylazo)-6-hydroxy-4-methyl-3--cyano-2- pyridones from ethyl 3-oxo-2-(substituted phenylazo)butanoates

Dostanic, Jasmina,Valentic, Natasa,Uscumlic, Gordana,Mijin, Dusan

experimental part, p. 499 - 504 (2012/02/03)

A new procedure for the synthesis of known azo pyridone dyes is presented. A series of 5-(substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2--pyridones were prepared from ethyl 3-oxo-2-(substituted phenylazo)butanoates and cyanoacetamide in acetone using potassium hydroxide as a catalyst by simple refluxing the reaction mixture. The structure of these dyes was confirmed by FT-IR, NMR and UV-Vis spectroscopy. Copyright 2011 (CC) SCS.
