Pentanedioic acid, 3,3-diphenyl-, also known as adipic acid, is an organic compound with the chemical formula (C6H5)2C(COOH)2. It is a white crystalline solid that is widely used in the production of nylon, a synthetic polymer. Adipic acid is derived from the oxidation of cyclohexanol or cyclohexanone, and it is also produced through the hydrolysis of adiponitrile. This dicarboxylic acid is an important industrial chemical, as it is a key component in the synthesis of various polymers, such as polyurethanes and polyesters. Its applications extend to the manufacturing of plastics, fibers, and resins, making it a versatile and essential compound in the chemical industry.
The CAS Registry Mumber 3531-22-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,3 and 1 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3531-22: (6*3)+(5*5)+(4*3)+(3*1)+(2*2)+(1*2)=64 64 % 10 = 4 So 3531-22-4 is a valid CAS Registry Number.
