Check Digit Verification of cas no

The CAS Registry Mumber 3819-20-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,1 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3819-20:
(6*3)+(5*8)+(4*1)+(3*9)+(2*2)+(1*0)=93
93 % 10 = 3
So 3819-20-3 is a valid CAS Registry Number.

Direct Conversion of 13β-Alkylgonatetraenes into 13β-Alkylgon-4-en-3-ones

Bijoy, Panicker,Ramachandran, Uma,Rao, G. S. R. Subba

, p. 2331 - 2334 (1994)

Birch reduction of 8,9-didehydroestradiol-17β 3-methyl ether 1 or 9(11)-didehydroestradiol-17β 3 methyl ether 2 followed by acid hydrolysis results in a mixture of 19-nortestosterone 8 and 19-nor-9β,10α-testosterone 9 in varying amounts.However, reduction of their acetates with sodium or lithium, tert-butyl alcohol in liquid ammonia and in the presence of aniline affords exclusively 19-nortestosterone.Similarly, 18α-homo-19-nortestosterone 12 is prepared from the acetate of 18α-homoestradiol-17β 3 methyl ether, 10.
