Terephthalsaeure-bis-(ethoxycarbonyl)-ester, also known as Terephthalic acid bis(2-ethoxyethyl) ester or simply Terephthalic acid diethyl glycol ester, is a chemical compound with the molecular formula C14H18O6. It is a colorless liquid with a density of 1.15 g/cm3 and a melting point of -35°C. This ester is derived from terephthalic acid, an important organic compound used in the production of polymers such as polyethylene terephthalate (PET). Terephthalic acid bis(ethoxycarbonyl)-ester is primarily used as a monomer in the synthesis of polyester resins and as a solvent for various applications. It is also known for its low toxicity and high boiling point, making it a suitable candidate for industrial processes.

Check Digit Verification of cas no

The CAS Registry Mumber 6668-01-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6668-01:
(6*6)+(5*6)+(4*6)+(3*8)+(2*0)+(1*1)=115
115 % 10 = 5
So 6668-01-5 is a valid CAS Registry Number.
