Check Digit Verification of cas no

The CAS Registry Mumber 1041-82-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,4 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1041-82:
(6*1)+(5*0)+(4*4)+(3*1)+(2*8)+(1*2)=43
43 % 10 = 3
So 1041-82-3 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.
