Dihydroxy-2α, 17β ethynyl-2β A-nor(5α)androstane is a complex organic compound belonging to the steroid family, specifically a derivative of androstane. This molecule features two hydroxyl groups at the 2α and 17β positions, an ethynyl group at the 17β position, and a nor structure at the 2β position, indicating the absence of a carbon atom in the steroid ring. The 5α configuration refers to the orientation of the hydroxyl group at the 5th carbon atom. dihydroxy-2α, 17β ethynyl-2β A-nor(5α)androstane is known for its potential applications in pharmaceuticals, particularly in the development of contraceptives and hormone therapies, due to its structural similarity to natural hormones and its ability to modulate hormonal activity.

Check Digit Verification of cas no

The CAS Registry Mumber 1038-20-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,3 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1038-20:
(6*1)+(5*0)+(4*3)+(3*8)+(2*2)+(1*0)=46
46 % 10 = 6
So 1038-20-6 is a valid CAS Registry Number.
