5-P-TOLYL-1H-PYRROLE-2-CARBOXYLIC ACID, also known as 2-(4-METHYLPHENYL)-1H-PYRROLE-5-CARBOXYLIC ACID, is an organic compound with the chemical formula C12H11NO2. 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. The molecule features a 4-methylphenyl group (p-tolyl) attached to the pyrrole ring at the 5-position and a carboxylic acid group at the 2-position. 5-P-TOLYL-1 H-PYRROLE-2-CARBOXYLIC ACID is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the production of herbicides and other chemical products. Its unique structure and properties make it a valuable building block in the development of new compounds with specific biological activities.

Check Digit Verification of cas no

The CAS Registry Mumber 131172-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,7 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131172-59:
(8*1)+(7*3)+(6*1)+(5*1)+(4*7)+(3*2)+(2*5)+(1*9)=93
93 % 10 = 3
So 131172-59-3 is a valid CAS Registry Number.

Haloform cleavage of 2-trifluoroacetyl- and N-vinyl-2-trifluoroacetylpyrroles gives pyrrole-2-carboxylic acids and their N-vinyl derivatives in good yields; most of these compounds do not melt between 120-190 deg C, but rather decompose with CO2 evolution.
