Check Digit Verification of cas no

The CAS Registry Mumber 77420-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,2 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77420-45:
(7*7)+(6*7)+(5*4)+(4*2)+(3*0)+(2*4)+(1*5)=132
132 % 10 = 2
So 77420-45-2 is a valid CAS Registry Number.

Aminolysis and Hydrolysis of Chromonyl Oxazolones and Some Condensation Reactions of 2-Methylchromone leading to Novel Chromones

Jones, Winton D.

, p. 344 - 348 (2007/10/02)

The aminolysis of 4--2-phenyl-1,3-oxazol-5(4H)-one with diethylamine gave N-benzamide.The hydrolysis of 2-methyl-4--1,3-oxazol-5(4H)-one gave the α-keto-acid, which could be converted into amino-acid derivatives.Condensation of 2-methylchromone with diethyl oxalate, 2-formyl-NN-diethylbenzamide, and 2-formylbenzoic acid gave the α-keto-acid, (E)-NN-diethyl-2-benzamide, and (E)-2-benzoic acid, respectively.
