α,α'-o-Phenylendiisobuttersaeure monomethylester, also known as monomethyl isophthalate, is an organic compound with the chemical formula C10H10O4. It is a derivative of isophthalic acid, where one of the carboxylic acid groups is esterified with methanol, resulting in a methyl ester group. This colorless, crystalline solid is widely used in the production of various polymers, particularly in the synthesis of polyethylene terephthalate (PET), a common plastic material. Monomethyl isophthalate is also employed as a chemical intermediate in the manufacturing of other esters, pharmaceuticals, and specialty chemicals. Its properties include a melting point of 65-67°C and a boiling point of 300°C. Due to its reactivity and versatility, it plays a significant role in the chemical industry.

Check Digit Verification of cas no
The CAS Registry Mumber 23116-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,1 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.Calculate Digit Verification of CAS Registry Number 23116-27:
(7*2)+(6*3)+(5*1)+(4*1)+(3*6)+(2*2)+(1*7)=70
70 % 10 = 0
So 23116-27-0 is a valid CAS Registry Number.
