The chemical compound "(3R,5S,8R,9S,10S,13S,14S,17R)-17-((R)-1-Hydroxy-ethyl)-10,13-dimethyl-2,3,4,5,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthrene-3,17-diol" is a complex, naturally occurring organic molecule. It is a stereoisomer with a specific arrangement of atoms in its structure, characterized by its chirality at multiple carbon centers (indicated by the R and S prefixes). (3R,5S,8R,9S,10S,13S,14S,17R)-17-((R)-1-Hydroxy-ethyl)-10,13-dimethyl-2,3,4,5,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthrene-3,17-diol belongs to the class of tetrahydro derivatives of cyclopenta[a]phenanthrenes, which are part of the larger family of polycyclic aromatic hydrocarbons. It features a hydroxyethyl group at the 17th carbon position and two methyl groups at the 10th and 13th carbon positions. The compound's structure is composed of a fused ring system with multiple hydroxyl and hydrogen atoms, making it a highly functionalized and potentially biologically active molecule.
The CAS Registry Mumber 59446-39-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,4,4 and 6 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 59446-39: (7*5)+(6*9)+(5*4)+(4*4)+(3*6)+(2*3)+(1*9)=158 158 % 10 = 8 So 59446-39-8 is a valid CAS Registry Number.
