CAS

  • or
The chemical in question is a complex polymer that is formed from the polymerization of α-D-Glucopyranoside, methyl, with 1,4-benzenedicarboxylic acid, 1,2-ethanediol, methyloxirane, oxirane, and 2,2'-oxybis[ethanol]. α-D-Glucopyranoside, methyl is a type of sugar derivative, while 1,4-benzenedicarboxylic acid, commonly known as terephthalic acid, is a key component in the production of polyesters. 1,2-ethanediol, or ethylene glycol, is a common solvent and precursor to polyesters. Methyloxirane, also known as propylene oxide, is a reactive compound used in the production of polyurethanes and other polymers. Oxirane, or ethylene oxide, is another important building block in polymer chemistry. Lastly, 2,2'-oxybis[ethanol], or diethylene glycol, is a viscous liquid used in the production of polyester resins and polyurethane foams. Together, these components form a polymer with a diverse range of potential applications, including in the production of plastics, fibers, and other materials.

Check Digit Verification of cas no

The CAS Registry Mumber 99770-02-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,7 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99770-02:
(7*9)+(6*9)+(5*7)+(4*7)+(3*0)+(2*0)+(1*2)=182
182 % 10 = 2
So 99770-02-2 is a valid CAS Registry Number.
