Disodium tetrafluorohydroquinone, also known as sodium tetrafluorohydroquinone dihydrate, is a chemical compound with the formula C6H4F4Na2O2. It is a white crystalline powder that is soluble in water and slightly soluble in ethanol. disodiumtetrafluorohydroquinone is primarily used as an antioxidant and a stabilizer in various industrial applications, including the manufacturing of polymers, plastics, and rubber. It helps prevent the oxidation of these materials, thereby extending their shelf life and improving their overall performance. Disodium tetrafluorohydroquinone is also known for its effectiveness in inhibiting the formation of peroxides, which can cause degradation in these materials. Its chemical structure, with four fluorine atoms attached to a hydroquinone backbone, contributes to its strong antioxidant properties.

Check Digit Verification of cas no

The CAS Registry Mumber 7640-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7640-65:
(6*7)+(5*6)+(4*4)+(3*0)+(2*6)+(1*5)=105
105 % 10 = 5
So 7640-65-5 is a valid CAS Registry Number.
