17β-hydroxy-17α-methyl-3-pyrrolidino-androsta-3,5-dien-11-one is a synthetic anabolic steroid derived from the androstane class, which is a modified version of the naturally occurring hormone testosterone. 17β-hydroxy-17α-methyl-3-pyrrolidino-androsta-3,5-dien-11-one is characterized by the presence of a hydroxyl group at the 17β position, a methyl group at the 17α position, and a pyrrolidino group at the 3 position. It is known for its potent anabolic and androgenic effects, which can lead to increased muscle mass, strength, and performance enhancement. However, it is important to note that the use of such substances is often associated with potential health risks and is regulated in many sports and medical contexts due to its potential for abuse and side effects.
The CAS Registry Mumber 981-61-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,8 and 1 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 981-61: (5*9)+(4*8)+(3*1)+(2*6)+(1*1)=93 93 % 10 = 3 So 981-61-3 is a valid CAS Registry Number.
