1,3-Benzenedicarboxylic acid, 5-(2-hydroxybenzoyl)-2-methyl-, diethyl ester is a complex organic compound with the chemical formula C21H20O8. It is derived from 1,3-benzenedicarboxylic acid, also known as isophthalic acid, which is a dicarboxylic acid with two carboxylic acid groups located at the 1 and 3 positions on a benzene ring. The compound features a 2-methyl group attached to the benzene ring and a 5-(2-hydroxybenzoyl) substituent, which is a benzoyl group with a hydroxyl group at the 2-position. The diethyl ester indicates that two ethoxy groups are attached to the carboxylic acid groups, forming esters. 1,3-Benzenedicarboxylic acid, 5-(2-hydroxybenzoyl)-2-methyl-, diethyl ester is used in the production of certain polymers and as a chemical intermediate in the synthesis of various pharmaceuticals and specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 57443-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,4 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57443-90:
(7*5)+(6*7)+(5*4)+(4*4)+(3*3)+(2*9)+(1*0)=140
140 % 10 = 0
So 57443-90-0 is a valid CAS Registry Number.
