64521-23-9 Usage
General Description
The chemical compound "1,3-benzenedicarboxylic acid, polymer with 2,2-dimethyl-1,3-propanediol, hexanedioic acid, 1,3-isobenzofurandione, and 2,2,4-trimethyl-1,3-pentanediol" is a polymer formed from the combination of several organic compounds. The presence of 1,3-benzenedicarboxylic acid and 2,2-dimethyl-1,3-propanediol indicates the presence of polyester building blocks. The addition of hexanedioic acid and 2,2,4-trimethyl-1,3-pentanediol may further enhance the polymer's properties, such as tensile strength and flexibility. 1,3-isobenzofurandione may also be contributing to the overall characteristics of the polymer, possibly adding thermal stability or resistance to UV radiation. This combination of chemicals likely results in a polymer with a range of useful properties for various applications.
Check Digit Verification of cas no
The CAS Registry Mumber 64521-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,2 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 64521-23:
(7*6)+(6*4)+(5*5)+(4*2)+(3*1)+(2*2)+(1*3)=109
109 % 10 = 9
So 64521-23-9 is a valid CAS Registry Number.
