1H-Pyrrole-3-carboxylic acid, 4,5-dihydro-1-methyl-4,5-dioxo-2-phenyl-, ethyl ester is a complex organic compound with the chemical formula C13H13NO3. It is a derivative of pyrrole, a heterocyclic aromatic organic compound consisting of a five-membered ring with one nitrogen atom and four carbon atoms. In this specific compound, the pyrrole ring is modified with a carboxylic acid group at the 3-position, a methyl group at the 1-position, and a phenyl group at the 2-position. The 4,5-dihydro and 4,5-dioxo groups indicate the presence of a double bond between the 4 and 5 carbon atoms, as well as two oxygen atoms in the form of a carbonyl group. The ethyl ester functional group is attached to the carboxylic acid, forming an ester linkage. 1H-Pyrrole-3-carboxylic acid, 4,5-dihydro-1-methyl-4,5-dioxo-2-phenyl-, 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 organic chemistry.

55404-27-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55404-27-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,4,0 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 55404-27:
(7*5)+(6*5)+(5*4)+(4*0)+(3*4)+(2*2)+(1*7)=108
108 % 10 = 8
So 55404-27-8 is a valid CAS Registry Number.
