The chemical compound "(3R,5S,7R,8R,9S,10S,12S,13R,14S,17R)-10,13-dimethyl-17-((R)-5-oxopentan-2-yl)hexadecahydro-1H-cyclopenta[a]phenanthrene-3,7,12-triyl triacetate" is a complex, naturally occurring organic molecule. It is characterized by its unique stereochemistry, with multiple chiral centers that give it a specific three-dimensional structure. The compound features a cyclopenta[a]phenanthrene core, which is a type of polycyclic aromatic hydrocarbon, and is further modified with a 10,13-dimethyl substitution and a 17-((R)-5-oxopentan-2-yl) side chain. The triacetate functional group indicates that three hydroxyl groups are esterified with acetic acid. This molecule is likely to be found in the realm of natural products chemistry, possibly with biological activity, given its intricate structure.
The CAS Registry Mumber 87899-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,9 and 9 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 87899-19: (7*8)+(6*7)+(5*8)+(4*9)+(3*9)+(2*1)+(1*9)=212 212 % 10 = 2 So 87899-19-2 is a valid CAS Registry Number.
