3,4'-diethyl-4,3'-dimethyl-1H,1'H-5,5'-methanediyl-bis-pyrrole-2-carboxylic acid is a complex organic compound characterized by its unique molecular structure. It features two pyrrole rings, which are heterocyclic aromatic organic compounds containing a nitrogen atom. The compound is bridged by a methanediyl group (-CH2-CH2-), creating a bis-pyrrole structure. The 3,4' positions on the pyrrole rings are substituted with ethyl groups (-CH2CH3), while the 4,3' positions are substituted with methyl groups (-CH3). The carboxylic acid functional groups (-COOH) are attached to the 2 positions of the pyrrole rings, endowing the compound with acidic properties. This chemical is known for its potential applications in various fields, including pharmaceuticals and materials science, due to its specific structural features and reactivity.
The CAS Registry Mumber 7670-43-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,7 and 0 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 7670-43: (6*7)+(5*6)+(4*7)+(3*0)+(2*4)+(1*3)=111 111 % 10 = 1 So 7670-43-1 is a valid CAS Registry Number.
