Check Digit Verification of cas no

The CAS Registry Mumber 1373936-72-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,9,3 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1373936-72:
(9*1)+(8*3)+(7*7)+(6*3)+(5*9)+(4*3)+(3*6)+(2*7)+(1*2)=191
191 % 10 = 1
So 1373936-72-1 is a valid CAS Registry Number.

A method for manufacturing the same and a new fluorocarbon deriv. triarylboron

-

Paragraph 0079; 0081; 0127-0129, (2018/08/25)

PROBLEM TO BE SOLVED: To provide a novel trichlorofluorocarbon derivative useful as a synthetic intermediate for pharmaceutical and agricultural chemicals and to provide its manufacturing method.SOLUTION: A trichlorofluorocarbon derivative represented by the general formula (1), where A represents a carbon atom or a nitrogen atom, Rrepresents a hydrogen atom, a methyl group, an ethyl group, a linear, branched or cyclic alkyl group having 3 to 10 carbon atoms, Rand Rrepresent condensed benzene rings or benzene rings into which substituents introduced when A is a carbon atom, Rrepresents a hydrogen atom and Rrepresents a hydrogen atom, a methyl group, an ethyl group, linear having 3 to 10 carbon atoms and the like, is obtained by reacting corresponding 2-position of trifluoromethanesulfonic acid ester with a base.
