Check Digit Verification of cas no
The CAS Registry Mumber 38673-36-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,6,7 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 38673-36:
(7*3)+(6*8)+(5*6)+(4*7)+(3*3)+(2*3)+(1*6)=148
148 % 10 = 8
So 38673-36-8 is a valid CAS Registry Number.

Synthesis of 13-alkyl-gon-4-ones
-
, (2008/06/13)
The preparation of 13-methylgon-4-enes and novel 13-polycarbonalkylgon-4-enes by a new total synthesis is described. 13-Alkylgon-4-enes having progestational, anabolic and androgenic activities are prepared by forming a tetracylic gonane structure unsaturated in the 1,3,5(10),9(11) and 14-positions, selectively reducing in the B- and C-rings, and converting the aromatic A-ring compounds so-produced to gon-4-enes by Birch reduction and hydrolysis.
