"Ent-11-fluoro-17β-methoxy-18α-(3,4,5-trimethoxy-benzoyloxy)-15β-yohimban-16α-carboxylic acid methyl ester" is a complex organic compound with a molecular formula of C31H37F3O9. It is a derivative of yohimban, a naturally occurring alkaloid found in the bark of the Pausinystalia yohimbe tree. This specific compound features a fluorine atom at the 11th position, a methoxy group at the 17β position, and a trimethoxy-benzoyloxy group at the 18α position. The 15β-yohimban-16α-carboxylic acid is esterified with a methyl group, which is indicated by the "methyl ester" part of the name. This chemical is of interest in the field of medicinal chemistry, particularly for its potential applications in the development of new drugs, due to its structural modifications that can alter the pharmacological properties of the parent yohimban alkaloid.
The CAS Registry Mumber 5080-80-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,8 and 0 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5080-80: (6*5)+(5*0)+(4*8)+(3*0)+(2*8)+(1*0)=78 78 % 10 = 8 So 5080-80-8 is a valid CAS Registry Number.
