A-nor-5α-cholest-3-en-1,2-dione is a steroidal compound derived from the cholesterol molecule. It is characterized by the absence of the A-ring (the first carbon ring) and the presence of a double bond at the 5α position. This molecule features a ketone group at the 1,2 positions, which is a carbonyl group (C=O) bonded to two carbon atoms. A-nor-5α-cholest-3-en-1,2-dione is an important intermediate in the synthesis of various steroidal drugs and hormones, as well as in the study of steroidal chemistry. Its unique structure allows for further functionalization and modification, making it a valuable compound in the field of organic chemistry and pharmaceuticals.

Check Digit Verification of cas no

The CAS Registry Mumber 1250-10-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1250-10:
(6*1)+(5*2)+(4*5)+(3*0)+(2*1)+(1*0)=38
38 % 10 = 8
So 1250-10-8 is a valid CAS Registry Number.

On the reaction of A-nor-5α-cholestan-2-one with benzeneseleninic anhydride

Morzycki, Jacek W.,Obidzinska, Jolanta

, p. 790 - 793 (2007/10/02)

A-Nor-5α-cholestan-2-one (1) was oxidized with BSA under various conditions.The stoichiometric reaction afforded diketones (3 and 4) and α-phenylseleno-ketone (2) while catalytic oxidation with the BSA/PhIO2/p-TsOH system resulted in lactones (7a and 7b) and anhydrides (5 and 6).The mechanism of these reactions is discussed. Key words:benzeneseleninic anhydride, A-nor-5α-cholestan-2-one, catalytic oxidation.
