Isophthalic acid di-p-tolyl ester is a chemical compound with the formula C₁₆H₁₄O₄. It is an ester derived from isophthalic acid and p-toluic acid, where two p-toluic acid molecules are esterified with one isophthalic acid molecule. isophthalic acid di-p-tolyl ester is characterized by its aromatic structure, with two phenyl rings (each containing a methyl group at the para position) attached to the isophthalic acid backbone. It is used in the production of specialty polymers and resins, such as polyimides and polyesters, due to its thermal stability and chemical resistance. The compound is also known for its potential applications in the synthesis of dyes and pharmaceuticals, highlighting its versatility in various chemical industries.

Check Digit Verification of cas no

The CAS Registry Mumber 4073-84-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,7 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4073-84:
(6*4)+(5*0)+(4*7)+(3*3)+(2*8)+(1*4)=81
81 % 10 = 1
So 4073-84-1 is a valid CAS Registry Number.
