Trimethyl 1-phenylpyrrole-2,3,4-tricarboxylate is a complex organic compound with the molecular formula C18H17NO6. It is characterized by a pyrrole ring, which is a five-membered aromatic ring containing four carbon atoms and one nitrogen atom. The pyrrole ring in trimethyl 1-phenylpyrrole-2,3,4-tricarboxylate is substituted with three carboxyl groups (-COOH) at the 2, 3, and 4 positions, and a phenyl group (C6H5) at the 1 position. The three carboxyl groups are each esterified with a methyl group (-CH3), resulting in the trimethyl ester form of the compound. This chemical is known for its potential applications in the synthesis of various pharmaceuticals and materials due to its unique structure and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 1042-89-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,4 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1042-89:
(6*1)+(5*0)+(4*4)+(3*2)+(2*8)+(1*9)=53
53 % 10 = 3
So 1042-89-3 is a valid CAS Registry Number.
