The trimethyl groups are likely attached to the nitrogen atom in the pyrrole ring, although the exact position is not specified. trimethyl 4,5-dimethoxy-1H-pyrrolo<2,3-f>quinoline-2,7,9-tricarboxylate is of interest in the field of organic chemistry and may have potential applications in the development of pharmaceuticals or other chemical products due to its unique structure and functional groups.
The CAS Registry Mumber 78891-39-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,9 and 1 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 78891-39: (7*7)+(6*8)+(5*8)+(4*9)+(3*1)+(2*3)+(1*9)=191 191 % 10 = 1 So 78891-39-1 is a valid CAS Registry Number.
