Terephthalic acid, commonly known as terephthyl, is an organic compound with the chemical formula C8H6O4. It is a white crystalline solid that is widely used in the production of polymers, particularly polyesters such as polyethylene terephthalate (PET). This versatile plastic is used in a variety of applications, including food and beverage containers, synthetic fibers, and films. Terephthalic acid is synthesized from p-xylene, which is derived from petroleum, and is an important intermediate in the chemical industry. Its properties include high melting and boiling points, and it is known for its stability and resistance to degradation, making it a valuable component in the creation of durable plastics and fibers.

Check Digit Verification of cas no

The CAS Registry Mumber 2468-28-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,6 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2468-28:
(6*2)+(5*4)+(4*6)+(3*8)+(2*2)+(1*8)=92
92 % 10 = 2
So 2468-28-2 is a valid CAS Registry Number.
