18-nor-5α,13β-androstan-17-one is a synthetic anabolic steroid derived from the naturally occurring hormone testosterone. It is characterized by the absence of a carbon atom at the 18th position in the steroid nucleus, which distinguishes it from other androstanes. This modification enhances its anabolic properties, making it a potent muscle-building agent. The 5α configuration refers to the orientation of a hydroxyl group at the 5th carbon, while the 13β-hydroxyl group indicates its position at the 13th carbon. These structural features contribute to the compound's specific biological activity. Primarily used in medical settings for conditions like anemia and osteoporosis, it has also been misused in sports for performance enhancement due to its ability to increase muscle mass and strength. However, its use is regulated and prohibited in many竞技体育 organizations due to potential health risks and ethical concerns.

4923-94-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4923-94-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,2 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.Calculate Digit Verification of CAS Registry Number 4923-94:
(6*4)+(5*9)+(4*2)+(3*3)+(2*9)+(1*4)=108
108 % 10 = 8
So 4923-94-8 is a valid CAS Registry Number.
