1,4-Pregnane-9α-fluoro-11β,17α,21-triol-3,20-dione 17,21-diacetate is a complex steroidal compound with a unique chemical structure. It is derived from the pregnane family of steroids, which are characterized by a cycloalkane ring system and multiple hydroxyl and carbonyl functional groups. The compound features a fluorine atom at the 9α position, three hydroxyl groups at the 11β, 17α, and 21 positions, and two carbonyl groups at the 3 and 20 positions. Additionally, it has two acetate groups esterified to the 17 and 21 hydroxyl groups, which contribute to its overall structure and properties. 1,4-pregnane-9α-fluoro-11β,17α,21-triol-3,20-dione 17,21-diacetate is of interest in the field of medicinal chemistry, particularly in the development of drugs targeting the endocrine system, due to its potential biological activities and unique structural features.
The CAS Registry Mumber 39987-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,8 and 7 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 39987-51: (7*3)+(6*9)+(5*9)+(4*8)+(3*7)+(2*5)+(1*1)=184 184 % 10 = 4 So 39987-51-4 is a valid CAS Registry Number.
