3,5-diphenyl-2,4-thiophenedicarboxylic acid is an organic compound with the chemical formula C18H12O4S. It is a derivative of thiophene, a heterocyclic compound consisting of a five-membered ring with one sulfur atom and four carbon atoms. The molecule features two phenyl groups attached to the 3rd and 5th carbon atoms of the thiophene ring, and two carboxylic acid groups at the 2nd and 4th positions. 3,5-diphenyl-2,4-thiophenedicarboxylic acid is known for its potential applications in the synthesis of various pharmaceuticals, dyes, and other organic compounds. It is typically synthesized through chemical reactions involving thiophene and phenyl derivatives, and its properties can be further modified by substituting the carboxylic acid groups with other functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 1457-24-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1457-24:
(6*1)+(5*4)+(4*5)+(3*7)+(2*2)+(1*4)=75
75 % 10 = 5
So 1457-24-5 is a valid CAS Registry Number.
