Androst-5-en-17-one, also known as 5-androst-17-one or 5-androstene-3-ol-17-one, is a naturally occurring steroid hormone in the human body that serves as a precursor to testosterone. It is predominantly produced in the testes, ovaries, and adrenal glands, playing a crucial role in the development of secondary sexual characteristics in both males and females. Beyond its physiological functions, Androst-5-en-17-one is utilized as a precursor for the synthesis of other hormones and pharmaceutical drugs, and has been investigated for its potential in hormone replacement therapy and as a performance-enhancing supplement in bodybuilding and athletics, although its use for these purposes is strictly regulated due to concerns about abuse and side effects.

Check Digit Verification of cas no

The CAS Registry Mumber 25824-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,2 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25824-80:
(7*2)+(6*5)+(5*8)+(4*2)+(3*4)+(2*8)+(1*0)=120
120 % 10 = 0
So 25824-80-0 is a valid CAS Registry Number.
