3,5-Dichlor-1-methyl-1H-pyrrol-2-carbonsaeure-methylester, also known as methyl 3,5-dichloro-1-methyl-1H-pyrrole-2-carboxylate, is a chemical compound with the molecular formula C7H7Cl2NO2. It is a derivative of pyrrole, a heterocyclic organic compound consisting of a five-membered aromatic ring with two carbon atoms and two nitrogen atoms. In this specific compound, the pyrrole ring is substituted with a methyl group at the 1-position, two chlorine atoms at the 3 and 5 positions, and a carboxylate group at the 2-position. The carboxylate group is further esterified with a methyl group, resulting in the formation of a methyl ester. 3,5-Dichlor-1-methyl-1H-pyrrol-2-carbonsaeure-methylester is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the production of herbicides and insecticides. Its chemical structure and properties make it a versatile building block for the development of new compounds with potential applications in various industries.

Check Digit Verification of cas no

The CAS Registry Mumber 1198-07-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1198-07:
(6*1)+(5*1)+(4*9)+(3*8)+(2*0)+(1*7)=78
78 % 10 = 8
So 1198-07-8 is a valid CAS Registry Number.
