It is a derivative of phenanthrene, a type of polycyclic aromatic hydrocarbon, with a carboxylic acid group that has been esterified with methanol to form a methyl ester. The compound has a chiral center at several positions, indicated by the R and S configurations, which determine its three-dimensional structure. It also contains a hydroxyethyl group attached to the 7th carbon, contributing to its unique properties. This molecule is characterized by its 12-membered ring structure, with three methyl groups attached at different positions, and a hydroxyethyl substituent. Such complex structures are often found in natural products and can have various biological activities, though the specific applications or properties of this particular compound are not detailed in the provided information.
The CAS Registry Mumber 7643-23-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 3 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 7643-23: (6*7)+(5*6)+(4*4)+(3*3)+(2*2)+(1*3)=104 104 % 10 = 4 So 7643-23-4 is a valid CAS Registry Number.
