516-54-1 Usage
Description
Allopregnanolone is an endogenous inhibitory pregnane neurosteroid that is synthesized from progesterone . It acts as a positive allosteric modulator of GABAA receptors at nM concentrations (exhibiting the greatest potentiation at isoforms containing δ subunits) and of GABAC receptors at μM concentrations. Allopregnanolone displays effects similar to other GABAA receptor potentiators such as benzodiazepines, including potent anticonvulsant, anxiolytic, and sedative activity.
Uses
(3α)-Allopregnanolone acts as a GABAA receptor positive allosteric modulator. (3α)-Allopregnanolone is a metabolite of Progesterone (P755900). (3α)-Allopregnanolone is a neuroactive steroid present in the blood and also the brain.

Check Digit Verification of cas no
The CAS Registry Mumber 516-54-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 516-54:
(5*5)+(4*1)+(3*6)+(2*5)+(1*4)=61
61 % 10 = 1
So 516-54-1 is a valid CAS Registry Number.

REGIOSELECTIVE REDUCTION OF POLYKETONES ON SILICA GEL SURFACE WITH BORANE-TRIMETHYLAMINE COMPLEX

, p. 61 - 64 (2007/10/02)
Steroidal diones and trione, bicyclic diones (7 and 8) and a tricyclic dione were adsorbed on silica gel and reduced with BH3*NMe3.The carbonyl groups at C-3 of the steroids, at C-4 of 7 and at C-3 of 8 were reduced regioselectively.The FT-IR spectra of 5α- and 5β-androstane-3,17-dione adsorbed on silica gel were measured.
