50718-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50718-35-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,7,1 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 50718-35:
(7*5)+(6*0)+(5*7)+(4*1)+(3*8)+(2*3)+(1*5)=109
109 % 10 = 9
So 50718-35-9 is a valid CAS Registry Number.

3-Keto-7 α,β-loweralkyl-Δ 5-steroids
-
, (2013/12/16)
7(α,β)-Loweralkyl-3-keto-Δ 5 -androstanes and 7(α,β)-loweralkyl-3-keto-Δ 5 -pregnanes having anabolic, androgenic, claudogenic, progestational and anti-progestational properties are prepared by reacting 3-keto-4,6-dienic androstanes and pregnanes with organocopper reagents such as dialkyllithium cuprate. The isomerization of these compounds to yield 7(α,β)-loweralkyl-3-keto-Δ 4 -steroids is also described.
