5-Bromo-6β-hydroxy-20-oxo-5α-pregnan-3β-yl acetate is a complex organic compound belonging to the steroid family, specifically a derivative of pregnane. It is characterized by the presence of a bromine atom at the 5th carbon position, a hydroxyl group at the 6β position, and an oxo group at the 20th carbon position. The 3β position is esterified with an acetate group, which is a common modification in steroid chemistry to alter the compound's properties. This molecule is of interest in medicinal chemistry due to its potential biological activities and applications, such as in the development of drugs targeting hormonal systems or other therapeutic areas where steroidal compounds play a role.

Check Digit Verification of cas no

The CAS Registry Mumber 2723-07-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,2 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2723-07:
(6*2)+(5*7)+(4*2)+(3*3)+(2*0)+(1*7)=71
71 % 10 = 1
So 2723-07-1 is a valid CAS Registry Number.

New Syntheses of 19,21-Dihydropregn-4-ene-3,20-dione, 21-Hydroxy-19-norpregn-4-ene-3,20-dione, and 11β,19,21-trihydroxypregn-4-ene-3,20-dione

19,21-Dihydroxypregn-4-ene-3,20-dione has been synthesized from 3β-acetoxypregn-5-en-20-one via the "hypoiodite reaction" , and Henbest acetoxylation at C-21; oxidation of the intermediate 21-monoacetate to 19-oxo derivative and alkaline cleavage gave 21-hydroxy-19-norpregn-4-ene-3,20-dione.A similar synthesis of 11β,19,21-trihydroxypregn-4-ene-3,20-dione from 3β-acetoxypregn-5-ene-11,20-dione proceeded through intermediates with the 11β-hydroxy function protected as its acetate.Unusual features mainly of conformational origin were observed in the presence of the 11β-acetoxy substituent; some were helpful to the synthesis, while others led to undesirable side reactions.
