Check Digit Verification of cas no

The CAS Registry Mumber 140163-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,6 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140163-89:
(8*1)+(7*4)+(6*0)+(5*1)+(4*6)+(3*3)+(2*8)+(1*9)=99
99 % 10 = 9
So 140163-89-9 is a valid CAS Registry Number.

Paragraph 0014, (2016/12/07)

PROBLEM TO BE SOLVED: To provide a method for producing O-ethyl S-n-propyl(E)-[2-(cyanoimino)-3-ethylimidazolidin-1-yl]phosphonothioate at high purity and high yield. SOLUTION: In this method, O-ethyl S-n-propyl(E)-[2-(cyanoimino)-3-ethylimidazolidin-1-yl]phosphonothioate is produced by making 2-(cyanoimino)-1-ethylimidazolidine react with O-ethyl-S-n-propylphosphorochloridethioate in the presence of an inert solvent and basic substance. In this method, as the basic substance, alkali metal hydroxide, alkaline earth metal hydroxide, or metal alkoxide is used. COPYRIGHT: (C)2013,JPOandINPIT
