3β-Acetoxy-5α-hydroxy-6β-fluor-17α-brom-pregnan-20-on is a complex steroidal compound characterized by its unique molecular structure. It features a pregnane core, which is a type of steroid with a four-ring structure. The compound is further defined by the presence of a hydroxyl group at the 5α position, an acetoxy group at the 3β position, a fluorine atom at the 6β position, and a bromine atom at the 17α position. The 20-on suffix indicates the presence of a ketone group at the 20th carbon. This specific arrangement of functional groups gives the molecule distinct chemical properties and potential biological activities, which may be of interest in pharmaceutical or chemical research.

Check Digit Verification of cas no

The CAS Registry Mumber 3664-91-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,6 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3664-91:
(6*3)+(5*6)+(4*6)+(3*4)+(2*9)+(1*1)=103
103 % 10 = 3
So 3664-91-3 is a valid CAS Registry Number.
