Pentanedioic acid, bis(4-methylphenyl) ester, also known as dimethyl diphenyl ester or bis(4-methylphenyl) pentanedioate, is an organic compound with the chemical formula C17H18O4. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. This ester is formed by the reaction of pentanedioic acid (glutaric acid) with two molecules of 4-methylphenol (para-cresol). It is used as a plasticizer, a substance added to plastics to increase their flexibility, and is also employed in the production of certain types of resins and adhesives. The compound is characterized by its molecular structure, which consists of a central pentanedioic acid backbone with two 4-methylphenyl groups attached to it via ester linkages.

Check Digit Verification of cas no

The CAS Registry Mumber 4649-00-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4649-00:
(6*4)+(5*6)+(4*4)+(3*9)+(2*0)+(1*0)=97
97 % 10 = 7
So 4649-00-7 is a valid CAS Registry Number.
