Ethyl 4-methoxy-5-oxo-1,2-diphenyl-2,5-dihydro-1H-pyrrole-3-carboxylate is a complex organic compound with the chemical formula C20H19NO4. It is a derivative of pyrrole, a heterocyclic aromatic organic compound consisting of a five-membered ring with two carbon atoms and two nitrogen atoms. This specific compound features a 1,2-diphenyl substitution, meaning it has two phenyl groups attached to the first and second carbon atoms of the pyrrole ring. Additionally, it contains a 4-methoxy group, which is a methoxy group (-OCH3) attached to the fourth carbon atom, and a 5-oxo group, indicating the presence of a carbonyl group (C=O) at the fifth position. The compound is further characterized by a 2,5-dihydro prefix, which signifies the presence of two hydrogen atoms attached to the second and fifth carbon atoms, and a 3-carboxylate group, which is a carboxylate ion (-COO-) attached to the third carbon atom. This molecule is an ester, formed by the reaction of the carboxylic acid group with an alcohol, in this case, ethanol. It is an important intermediate in the synthesis of various pharmaceuticals and has potential applications in the development of new drugs.

Check Digit Verification of cas no

The CAS Registry Mumber 6940-07-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6940-07:
(6*6)+(5*9)+(4*4)+(3*0)+(2*0)+(1*7)=104
104 % 10 = 4
So 6940-07-4 is a valid CAS Registry Number.
