Check Digit Verification of cas no

The CAS Registry Mumber 157977-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,9,7 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157977-50:
(8*1)+(7*5)+(6*7)+(5*9)+(4*7)+(3*7)+(2*5)+(1*0)=189
189 % 10 = 9
So 157977-50-9 is a valid CAS Registry Number.

Synthesis of 3-carboxy-20-keto steroid, SB 209963, a 5α-reductase inhibitor, by palladium-catalyzed hydroxycarbonylation

Yu, Marvin S.,Baine, Neil H.

, p. 3123 - 3124 (2007/10/03)

SB 209963 was produced in three steps starting from 17β- carboxyandrost-4-en-3-one. A palladium-catalyzed hydroxycarbonylation introduced the carboxylic acid under mild conditions withOUt epimerization at C17. This reaction represents the first example of hydroxycarbonylation of a vinyl halide under neutral conditions.
