The chemical compound "(+/-)-3-hydroxy-13r-methyl-(14tH)-11,12,13,14,15,16-hexahydro-11H-cyclopenta[a]phenanthren-17-one" is a complex organic molecule with a unique structure. It features a cyclopenta[a]phenanthren-17-one core, which is a type of polycyclic aromatic hydrocarbon. The molecule is characterized by a 3-hydroxy group, indicating the presence of a hydroxyl functional group at the 3rd carbon position. Additionally, it has a 13r-methyl group, which is a methyl group attached to the 13th carbon in a specific spatial orientation. The compound is also hexahydro, meaning it contains six hydrogen atoms that are part of a saturated ring structure. The 11H-cyclopenta[a]phenanthren-17-one part of the name indicates that the molecule has a hydrogen atom at the 11th position and a carbonyl group at the 17th position, which together form a ketone functional group. (+/-)-3-hydroxy-13r-methyl-(14tH)-11,12,13,14,15,16-hexahydro-11H-cyclopenta[a]phenanthren-17-one is a racemic mixture, denoted by the (+/-) symbol, meaning it contains equal amounts of both the R and S enantiomers.
The CAS Registry Mumber 632-38-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 2 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 632-38: (5*6)+(4*3)+(3*2)+(2*3)+(1*8)=62 62 % 10 = 2 So 632-38-2 is a valid CAS Registry Number.
