5190-31-8 Usage
General Description
3-keto-5,10-epoxy-19-normethylandrostan-17-one is a synthetic steroid compound with an epoxide and a ketone functional group. It is derived from the hormone testosterone and is known for its anabolic effects, making it popular among bodybuilders and athletes. 3-keto-5,10-epoxy-19-normethylandrostan-17-one has the potential to increase muscle mass and strength and enhance athletic performance. However, its use is regulated in many sports organizations and is considered a controlled substance in many countries due to its potential for misuse and adverse health effects. As with all steroid compounds, 3-keto-5,10-epoxy-19-normethylandrostan-17-one should be used with caution and under the supervision of a healthcare professional.
Check Digit Verification of cas no
The CAS Registry Mumber 5190-31-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5190-31:
(6*5)+(5*1)+(4*9)+(3*0)+(2*3)+(1*1)=78
78 % 10 = 8
So 5190-31-8 is a valid CAS Registry Number.

Synthesis, reactions, conformation analysis, and NMR spectra of 5,10-epoxy-5ξ,10ξ-estrane-3,17-diones

, p. 507 - 518 (2007/10/03)
On epoxidation of estr-5(10)-ene-3,17-dione, the 5β,10β-epoxide is the major product. The mixture of epoxides was converted into 5,10β-dihydroxy-5α-estrane-3,17-dione, 10α- and 10β-hydroxyestr-4-ene-3,17-dione, and estrone. Due to the sensitivity of the products, 1H NMR was the best way to monitor the reaction pathway.
