Check Digit Verification of cas no

The CAS Registry Mumber 74402-76-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,0 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74402-76:
(7*7)+(6*4)+(5*4)+(4*0)+(3*2)+(2*7)+(1*6)=119
119 % 10 = 9
So 74402-76-9 is a valid CAS Registry Number.

Preparations of carboxylic acid esters containing heptafluoroisopropyl groups

Suyama, T.,Kato, S.,Mizutani, Y.

, p. 93 - 99 (2007/10/02)

The reaction of fluoroglyoxylic acid esters and fluoroformic acid esters with perfluoropropene (PFP) yielded perfluoro(3-methyl-2-oxobutyric) acid esters and perfluoroisobutyric acid esters, respectively.Oxamide derivatives and 2,3-quinoxalinediol have been prepared by the reaction of perfluoro(3-methyl-2-oxobutyric) acid esters with amines and o-phenylenediamine, respectively.Perfluoro(3-methyl-2-oxobutyric) acid esters give perfluoroisobutyric acid esters on heating in the presence of fluoride ion in an aprotic solvent.
