2β-Methyl-17β-hydroxy-oestr-4-en-3-on, also known as Methyltrienolone or R1881, is a synthetic steroid hormone that belongs to the class of androgens. It is structurally similar to dihydrotestosterone (DHT), with a methyl group at the 2β position and a hydroxyl group at the 17β position. 2β-Methyl-17β-hydroxy-oestr-4-en-3-on is used in medical research to study the effects of androgens on various physiological processes, such as muscle growth, bone density, and sexual development. Methyltrienolone is not approved for clinical use in humans, but it has been utilized in scientific studies to understand the role of androgens in health and disease. Its chemical structure and properties make it a valuable tool for investigating the mechanisms of action of androgens in the body.

3919-20-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3919-20-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3919-20:
(6*3)+(5*9)+(4*1)+(3*9)+(2*2)+(1*0)=98
98 % 10 = 8
So 3919-20-8 is a valid CAS Registry Number.
