(8R,13R,14R)-17-Hydroxy-13-methyl-1,2,6,7,8,11,12,13,14,15,16,17-dodecahydro-cyclopenta[a]phenanthren-3-one is a complex organic compound with a molecular formula of C19H30O2. It is a stereoisomer, specifically a tricyclic diterpene, characterized by its unique arrangement of atoms and functional groups. The compound features a cyclopenta[a]phenanthren-3-one core, which is a type of polycyclic aromatic hydrocarbon, and is further modified by the presence of a hydroxyl group at the 17th carbon position and a methyl group at the 13th carbon position. The numbering and stereochemistry (R configuration) at the 8th, 13th, and 14th carbons are crucial for its specific identity and biological activity. (8R,13R,14R)-17-Hydroxy-13-methyl-1,2,6,7,8,11,12,13,14,15,16,17-dodecahydro-cyclopenta[a]phenanthren-3-one is of interest in the field of natural products chemistry, potentially for its pharmacological properties or as a precursor in the synthesis of other bioactive molecules.
The CAS Registry Mumber 4019-90-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,1 and 9 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4019-90: (6*4)+(5*0)+(4*1)+(3*9)+(2*9)+(1*0)=73 73 % 10 = 3 So 4019-90-3 is a valid CAS Registry Number.
