Uses

17,17-Dimethyl-18-norandrosta-1,4,13-trien-3-one is a anabolic-androgenic steroid and a chemical derivative of Methandrostenolone (M226000).

Check Digit Verification of cas no

The CAS Registry Mumber 77702-25-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,0 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77702-25:
(7*7)+(6*7)+(5*7)+(4*0)+(3*2)+(2*2)+(1*5)=141
141 % 10 = 1
So 77702-25-1 is a valid CAS Registry Number.

Studies on anabolic steroids. 9. Tertiary sulfates of anabolic 17α-methyl steroids: synthesis and rearrangement

Bi, Honggang,Masse, Robert,Just, George

, p. 306 - 312 (2007/10/02)

A simple and convenient method has been developed to prepare sulfates of anabolic 17β-hydroxy-17α-methyl steroids.The sulfates of methandienone, 17α-methyltestosterone, mestanolone, oxandrolone, and stanozolol were prepared.Different A-ring functions were not affected under the sulfation condition.The buffered hydrolyses of these sulfates provided the 17-epimers of the original steroids and 17,17-dimethyl-18-nor-13(14)-ene steroids, presumably via the 17-carbocations. Keywords: steroids, tertiary sulfates; 17α-methyl steroids; 17β-methyl steroids; 17,17-dimethyl-18-norandrost-13(14)-enes; NMR
