"Ent-11,17β-dimethoxy-18α-salicyloyloxy-15β-yohimban-16α-carboxylic acid methyl ester" is a complex organic compound belonging to the class of yohimban alkaloids, which are naturally occurring substances found in plants. This specific compound is characterized by its unique molecular structure, featuring a 16α-carboxylic acid group, a methyl ester at the 16α position, and a salicyloyloxy group at the 18α position. It also contains two methoxy groups at the 11 and 17β positions. These structural features contribute to its potential biological activities and pharmacological properties, which are of interest in the field of natural product chemistry and drug discovery. The compound's name reflects its stereochemistry and functional groups, indicating that it is an ent-isomer, which means it is a stereoisomer of the natural yohimban alkaloids but with the opposite configuration at certain chiral centers.
The CAS Registry Mumber 2871-55-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,7 and 1 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2871-55: (6*2)+(5*8)+(4*7)+(3*1)+(2*5)+(1*5)=98 98 % 10 = 8 So 2871-55-8 is a valid CAS Registry Number.
