1H-Pyrrole-3-carboxylic acid, 2-acetyl-5-methyl, ethyl ester is a complex organic compound with the chemical formula C10H11NO3. It is a derivative of pyrrole, a heterocyclic aromatic organic compound consisting of a five-membered ring with four carbon atoms and one nitrogen atom. In this specific compound, the pyrrole ring is substituted with a carboxylic acid group at the 3-position, an acetyl group at the 2-position, and a methyl group at the 5-position. The carboxylic acid group is further esterified with an ethyl group, forming an ethyl ester. 1H-Pyrrole-3-carboxylic acid, 2-acetyl-5-methyl-, ethyl ester is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, as well as its role as an intermediate in the production of certain dyes and pigments. Its unique structure and properties make it an interesting target for researchers in the field of organic chemistry.
The CAS Registry Mumber 90433-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,3 and 3 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 90433-83: (7*9)+(6*0)+(5*4)+(4*3)+(3*3)+(2*8)+(1*3)=123 123 % 10 = 3 So 90433-83-3 is a valid CAS Registry Number.
