It is characterized by the presence of a fluorine atom at the 9α position, two hydroxyl groups at the 17α and 21 positions, and a methyl group at the 16α position. The molecule also features a pregnadiene core with a double bond between carbons 1 and 4, and three ketone groups at the 3, 11, and 20 positions. The 21-acetate group indicates the presence of an acetyl group attached to the hydroxyl group at the 21 position. 9α-fluoro-17α,21-dihydroxy-16α-methyl-1,4-pregnadiene-3,11,20-trione 21-acetate is a derivative of the pregnane class of steroids and is known for its potent anti-inflammatory and immunosuppressive properties, making it a valuable compound in the field of pharmaceuticals, particularly in the development of drugs for conditions such as rheumatoid arthritis and organ transplantation.
The CAS Registry Mumber 2995-86-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,9 and 5 respectively; the second part has 2 digits, 8 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2995-86: (6*2)+(5*9)+(4*9)+(3*5)+(2*8)+(1*6)=130 130 % 10 = 0 So 2995-86-0 is a valid CAS Registry Number.
