Check Digit Verification of cas no

The CAS Registry Mumber 139571-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,7 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139571-76:
(8*1)+(7*3)+(6*9)+(5*5)+(4*7)+(3*1)+(2*7)+(1*6)=159
159 % 10 = 9
So 139571-76-9 is a valid CAS Registry Number.

1-TRIFLUOROMETHYL-2-CHLOROETHYLTHIOLATED CARBONYL COMPOUNDS: SYNTHESIS AND PROPERTIES

Sizov, A. Yu.,Kolomiets, A. F.,Fokin, A. V.

, p. 592 - 596 (1991)

1-Trifluoromethyl-2-chloroethylsulfenyl chloride thiolates enolizible ketones, forming products of mono- and disubstitution.The properties of the resultant sulfides are determined by the presence in the molecule of two acidic CH centres.Thus, bromination proceeds at the ambient center and reaction with bases leads to (1-trifluoromethylvinyl) sulfides which are able to undergo intramolecular cyclizations and Diels-Alder reactions.
