"16α,17α-Epoxy-3,20-dioxo-16β-methyl-Δ4-pregnen" is a complex steroidal compound characterized by a unique molecular structure. It features a pregnane core, which is a type of steroid with a four-ring structure. The compound is distinguished by the presence of an epoxy group at the 16α and 17α positions, which introduces a three-membered oxygen-containing ring into the molecule. Additionally, it has a methyl group at the 16β position, contributing to its stereochemistry. The Δ4 notation indicates that the compound has a double bond between the fourth and fifth carbon atoms in one of the rings. The 3,20-dioxo part of the name signifies the presence of two carbonyl groups, one at the 3-position and another at the 20-position, which are key functional groups in steroid chemistry. 16α,17α-Epoxy-3,20-dioxo-16β-methyl-Δ4-pregnen is of interest in the field of organic chemistry and may have potential applications in pharmaceuticals or as a precursor in the synthesis of other steroidal compounds.
The CAS Registry Mumber 1443-96-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,4 and 3 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1443-96: (6*1)+(5*4)+(4*4)+(3*3)+(2*9)+(1*6)=75 75 % 10 = 5 So 1443-96-5 is a valid CAS Registry Number.
