3β,17α-Diacetoxy-20-oxo-16-methylen-Δ5-pregnen is a complex steroidal compound characterized by its unique molecular structure. It features a pregnane core, which is a type of steroid with a specific carbon skeleton. The Δ5-pregnen designation indicates that the compound has a double bond between the 5th and 6th carbon atoms. The 3β and 17α positions are acetylated, meaning they each have an acetate group attached, which are common functional groups in steroid chemistry. The 20-oxo group signifies the presence of a carbonyl group at the 20th carbon, and the 16-methylen group indicates a double bond between the 16th and 17th carbons with a methyl group attached to the 16th carbon. 3β,17α-Diacetoxy-20-oxo-16-methylen-Δ5-pregnen is a derivative of pregnenolone, a naturally occurring steroid hormone, and is often used in the synthesis of other steroidal compounds due to its reactive functional groups and structural features.
The CAS Registry Mumber 862-35-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 2 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 862-35: (5*8)+(4*6)+(3*2)+(2*3)+(1*5)=81 81 % 10 = 1 So 862-35-1 is a valid CAS Registry Number.
