96837-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 96837-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,8,3 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 96837-97:
(7*9)+(6*6)+(5*8)+(4*3)+(3*7)+(2*9)+(1*7)=197
197 % 10 = 7
So 96837-97-7 is a valid CAS Registry Number.

SYNTHESIS OF STEROID 24,20-LACTONES BY MEANS OF PENYLSELENOLACTONIZATION
Kocor, Marian,Bersz, Beata
, p. 197 - 204 (2007/10/02)
A synthesis of (20 R)- and (20 S)-3β-methoxy-5-cholen-24,20-lactones (7a and 7b) from 3β-methoxy-5-androsten-17-one (2) is described.The 17-ketone 2 was treated with isopropenyllithium to give 3β-methoxy-17α-(prop-1'-en-2'-ylo)-5-androsten-17β-ol.(3) Comp
