1,3-Benzenedicarboxylic acid polymer with 1,3-propanediol, commonly known as polytrimethylene terephthalate (PTT), is a type of polyester polymer that is formed through the condensation reaction of 1,3-benzenedicarboxylic acid (isophthalic acid) and 1,3-propanediol (trimethylene glycol). PTT exhibits unique properties such as excellent elasticity, strength, and resistance to UV radiation, making it suitable for various applications, including textiles, carpets, and engineering plastics. The polymer's structure allows for improved dyeability and stain resistance compared to other polyesters, while also offering better moisture management and softness. PTT is known for its sustainability and biodegradability, contributing to its growing popularity in eco-friendly applications.

Check Digit Verification of cas no

The CAS Registry Mumber 33114-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,1 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33114-65:
(7*3)+(6*3)+(5*1)+(4*1)+(3*4)+(2*6)+(1*5)=77
77 % 10 = 7
So 33114-65-7 is a valid CAS Registry Number.
