A-Nor-5α-androstan-2,16-dion, also known as 5α-androstane-2,16-dione, is a synthetic anabolic steroid derived from the naturally occurring hormone testosterone. It is characterized by the absence of a carbon atom at the 1-position (hence the term "A-Nor") and the presence of a double bond between carbons 1 and 2. This modification results in increased anabolic effects and reduced androgenic side effects compared to its parent compound. A-Nor-5α-androstan-2,16-dion is used in medical and sports contexts to promote muscle growth, enhance athletic performance, and treat conditions like muscle wasting and osteoporosis. However, its use is controversial due to potential health risks and its classification as a performance-enhancing drug in many sports.
The CAS Registry Mumber 1616-32-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,1 and 6 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1616-32: (6*1)+(5*6)+(4*1)+(3*6)+(2*3)+(1*2)=66 66 % 10 = 6 So 1616-32-6 is a valid CAS Registry Number.
