The chemical compound "(1R,4aS,7R,10aR)-7-(2-Acetoxy-ethyl)-1,4a,7-trimethyl-9-oxo-1,2,3,4,4a,5,6,7,8,9,10,10a-dodecahydro-phenanthrene-1-carboxylic acid methyl ester" is a complex organic molecule with a highly specific stereochemistry. It features a phenanthrene core, which is a type of polycyclic aromatic hydrocarbon, and is characterized by its 12-membered ring structure. The compound has three methyl groups attached at positions 1, 4a, and 7, and a 9-oxo group indicating the presence of a carbonyl group at the 9th position. A 2-acetoxy-ethyl side chain is attached at the 7th position, and the carboxylic acid group is esterified with a methyl group, making it a methyl ester. This molecule is a derivative of a naturally occurring compound and is often found in the resin of certain plants. Due to its complexity, it is typically synthesized for use in research or as an intermediate in the production of other chemicals.
The CAS Registry Mumber 2319-77-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,1 and 9 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 2319-77: (6*2)+(5*3)+(4*1)+(3*9)+(2*7)+(1*7)=79 79 % 10 = 9 So 2319-77-9 is a valid CAS Registry Number.
