1-Methylestra-1,3,5(10)-triene-3,17β-diol 17-acetate, also known as Methyltestosterone or Metandienone, is a synthetic and orally active androgen and anabolic steroid. It is a derivative of dihydrotestosterone (DHT), with a methyl group added to the 1α position and an acetate ester at the 17β position. This modification allows the compound to be orally active, as it can be absorbed through the digestive system. Methyltestosterone is used medically to treat conditions like delayed puberty, low testosterone levels, and breast cancer in women. It is also used off-label for performance enhancement in sports and bodybuilding due to its anabolic effects on muscle and bone. However, it is important to note that the use of anabolic steroids for non-medical purposes is illegal and can lead to serious health risks.
The CAS Registry Mumber 2456-11-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,5 and 6 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2456-11: (6*2)+(5*4)+(4*5)+(3*6)+(2*1)+(1*1)=73 73 % 10 = 3 So 2456-11-3 is a valid CAS Registry Number.
