Check Digit Verification of cas no
The CAS Registry Mumber 20817-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,1 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20817-34:
(7*2)+(6*0)+(5*8)+(4*1)+(3*7)+(2*3)+(1*4)=89
89 % 10 = 9
So 20817-34-9 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.
