1,4-Benzenedicarboxylic acid, bis[(tetrahydro-2-furanyl)methyl] ester, also known as bis(tetrahydrofurfuryl) terephthalate (BTFT), is a chemical compound derived from terephthalic acid. It is formed by the esterification of terephthalic acid with two molecules of tetrahydrofurfuryl alcohol, resulting in a diester. BTFT is a colorless, viscous liquid with a molecular weight of 298.3 g/mol. 1,4-Benzenedicarboxylic acid, bis[(tetrahydro-2-furanyl)methyl] ester is primarily used as a monomer in the production of various polymers, such as poly(butylene terephthalate) (PBT) and poly(ethylene terephthalate) (PET), which are widely used in the manufacturing of plastics, fibers, and films. BTFT is also known for its low toxicity, high thermal stability, and excellent mechanical properties, making it a valuable component in the chemical industry.

The CAS Registry Mumber 4623-50-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,2 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.Calculate Digit Verification of CAS Registry Number 4623-50:
(6*4)+(5*6)+(4*2)+(3*3)+(2*5)+(1*0)=81
81 % 10 = 1
So 4623-50-1 is a valid CAS Registry Number.
