2137-38-4 Usage
General Description
(17beta)-17-hydroxy-2-methylideneandrost-4-en-3-one, also known as mesterolone, is a synthetic androgen and anabolic steroid. It is derived from testosterone and is used medically to treat low testosterone levels in men and androgen deficiency in women. Mesterolone works by increasing the production of the male hormone testosterone, which can help to improve muscle growth, libido, and overall energy levels. It is also sometimes used by bodybuilders and athletes to enhance athletic performance and muscle mass. However, mesterolone can have various side effects, including liver toxicity, and should only be taken under the supervision of a healthcare professional.Check Digit Verification of cas no
The CAS Registry Mumber 2137-38-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.Calculate Digit Verification of CAS Registry Number 2137-38:
(6*2)+(5*1)+(4*3)+(3*7)+(2*3)+(1*8)=64
64 % 10 = 4
So 2137-38-4 is a valid CAS Registry Number.
