Check Digit Verification of cas no

The CAS Registry Mumber 44969-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,4,9,6 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 44969-80:
(7*4)+(6*4)+(5*9)+(4*6)+(3*9)+(2*8)+(1*0)=164
164 % 10 = 4
So 44969-80-4 is a valid CAS Registry Number.

A NEW METHOD FOR THE PRODUCTION OF UNSATURATED PERFLUORINATED CARBOXYLIC ACIDS

Plashkin, V. S.,Zapevalova, T. B.,Zapevalov, A. Ya.,Selishchev, B. N.

, p. 467 - 469 (2007/10/02)

A new method is described for the production of unsaturated perfluorinated carboxylic acids, involving the oxidation of fluoroalkanes with the general formula H(CF2)nCFClCF2Cl, where n=2, 4, or 6, by a mixture of chlorine and nitrogen oxides at 500 deg C with subsequent dechlorination of the obtained acids HOOC(CF2)n-1CFClCF2Cl with zinc dust in a solvent.
