115940-37-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115940-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,9,4 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 115940-37:
(8*1)+(7*1)+(6*5)+(5*9)+(4*4)+(3*0)+(2*3)+(1*7)=119
119 % 10 = 9
So 115940-37-9 is a valid CAS Registry Number.

Synthesis of new inhibitors of aldosterone biosynthesis
Viger, Antoinette,Coustal, Suzy,Perard, Serge,Marquet, Andree
, p. 1127 - 1134 (2007/10/02)
The synthesis of 18 vinyl and 18 ethynylprogesterone 1 and 2 is described. The reported data emphasize the decisive role played by the protective group on carbon 3 in the course of reactions taking place at the angular 18 methyl group. Compounds 1 and 2, designed as kcat inhibitors of aldosterone biosynthesis late step show substantial in vitro activity.
