3-Methylen-19-norandrost-4-en-17-on, also known as 3-methyl-19-nortestosterone or 3-methyl-19-nor-4-androsten-17-one, is a synthetic anabolic steroid derived from testosterone. It is characterized by the presence of a double bond between carbons 1 and 2 (3-methylen), the absence of a carbon atom at position 19 (19-norandrost), and a ketone group at position 17 (17-on). 3-Methylen-19-norandrost-4-en-17-on is known for its potent anabolic effects, which can promote muscle growth and strength, and its androgenic properties, which can influence secondary sexual characteristics. It is used in medical settings for conditions like delayed puberty, muscle wasting, and osteoporosis, and is also used illicitly for performance enhancement in sports. However, its use is associated with potential side effects and health risks, including liver toxicity, hormonal imbalances, and cardiovascular issues.

Check Digit Verification of cas no

The CAS Registry Mumber 3549-33-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,4 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3549-33:
(6*3)+(5*5)+(4*4)+(3*9)+(2*3)+(1*3)=95
95 % 10 = 5
So 3549-33-5 is a valid CAS Registry Number.
