1,2-Benzenedicarboxylic acid, 3,4,5,6-tetrachloro-, dioctyl ester is a chemical compound with the molecular formula C24H32Cl4O4. It is an ester derivative of 1,2-benzenedicarboxylic acid, also known as phthalic acid, with four chlorine atoms substituted at the 3,4,5, and 6 positions. The compound is formed by the reaction of phthalic acid with two octyl alcohol molecules, resulting in a diester. This chemical is characterized by its high molecular weight, low solubility in water, and high boiling point. It is primarily used as a plasticizer in the production of flexible polyvinyl chloride (PVC) products, providing improved flexibility, durability, and resistance to heat and chemicals. Due to its potential health and environmental concerns, its use is regulated in certain applications, and alternatives are being developed to reduce exposure and environmental impact.

The CAS Registry Mumber 3475-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,7 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 3475-91:
(6*3)+(5*4)+(4*7)+(3*5)+(2*9)+(1*1)=100
100 % 10 = 0
So 3475-91-0 is a valid CAS Registry Number.
