Check Digit Verification of cas no

The CAS Registry Mumber 188531-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,5,3 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 188531-19:
(8*1)+(7*8)+(6*8)+(5*5)+(4*3)+(3*1)+(2*1)+(1*9)=163
163 % 10 = 3
So 188531-19-3 is a valid CAS Registry Number.

Synthesis and Reactions of 3-(Nosyloxy)-2-keto Esters

Hoffman, Robert V.,Catherine Johnson,Okonya, John F.

, p. 2458 - 2465 (1997)

A series of 3-(nosyloxy)-2-keto esters 7a-j were prepared from the corresponding α-keto esters by conversion to the trimethylsilyl enol ether and reaction with p-nitrobenzenesulfonyl peroxide. Conversion of these materials to 1,2,3-trifunctionalized compounds is described, and comparison of their properties with isomeric 2-(nosyloxy)-3-keto esters is discussed.
