"Ent-11,17β-dimethoxy-18α-(2-methoxy-5-nitro-benzoyloxy)-15β-yohimban-16α-carboxylic acid methyl ester" is a complex organic compound with a molecular formula of C34H41NO10. It is a derivative of yohimban-16α-carboxylic acid, which is a naturally occurring alkaloid found in the bark of the African tree Pausinystalia yohimbe. This specific compound features a 15β-yohimban-16α-carboxylic acid core, with a methyl ester group at the 16α position, two methoxy groups at the 11 and 17β positions, and a 2-methoxy-5-nitro-benzoyloxy group attached to the 18α position. The presence of the nitro group and the benzoyloxy moiety suggests that ent-11,17β-dimethoxy-18α-(2-methoxy-5-nitro-benzoyloxy)-15β-yohimban-16α-carboxylic acid methyl ester may have been synthesized for specific pharmacological or chemical properties, potentially related to its ability to interact with biological targets. The complexity of the structure indicates that it is likely a product of advanced organic synthesis and may have applications in the field of medicinal chemistry or as a research tool in the study of natural products and their derivatives.
The CAS Registry Mumber 3049-82-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,4 and 9 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3049-82: (6*3)+(5*0)+(4*4)+(3*9)+(2*8)+(1*2)=79 79 % 10 = 9 So 3049-82-9 is a valid CAS Registry Number.
