31025-33-9 Usage
Description
(4R,17beta)-17-hydroxy-10-methyl-4,9-cyclo-9,10-secoandrost-5-en-1-one, also known as mesterolone, is an androgen and anabolic steroid (AAS) medication. It is used in the treatment of low testosterone levels in men, and has also been used to treat male infertility and male hypogonadism. Mesterolone works by increasing the amount of testosterone in the body, leading to improved energy levels, muscle mass, and libido. It is typically taken by mouth and comes in the form of a tablet. However, it may have potential side effects such as liver problems, mood changes, and irregular heartbeat, and should only be used under the supervision of a healthcare professional.

Check Digit Verification of cas no
The CAS Registry Mumber 31025-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,2 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31025-33:
(7*3)+(6*1)+(5*0)+(4*2)+(3*5)+(2*3)+(1*3)=59
59 % 10 = 9
So 31025-33-9 is a valid CAS Registry Number.

Synthesis and Carbon-13 Nuclear Magnetic Resonance Studies of Δ5 and Saturated 4,4-Disubstituted 3-Ketosteroids
Rizvi, Syed Q. A.,Williams, John R.
, p. 1127 - 1132 (2007/10/02)
A number of Δ5-4,4-dialkyl-3-ketosteroids were synthesized by alkylation of steroidal 4-en-3-ones via their enolate anions.Carbon-13 nuclear magnetic resonance spectra of these compounds were measured and assigned.Predicted carbon shifts show fairly good agreement with the observed values in the estrenone series.The deviations for androstenones and cholestenones were interpreted in terms of conformational changes in the steroid skeleton which arise from nonbonded 1,5-interactions (δ-effect) between the 19-methyl and the 4,4 substituents.Comparison of the carbon shifts for 4,4-dimethyl-3-ketosteroids with the appropriate Δ5derivatives did not indicate any "conformational transmission" in the latter compounds.The observed carbon shift differences for C-14 seem to arise solely from the presence of the 19-methyl group.
