1,1-Difluoro-2,2-diiodoethene, also known as difluorodiiodovinylene, is an organofluorine compound with the chemical formula C2F2I2. It is a colorless, volatile liquid that is sensitive to light and heat. This molecule features a vinylene (ethene) backbone with two fluorine atoms attached to one carbon atom and two iodine atoms attached to the other carbon atom. Due to the presence of both electronegative fluorine and electron-withdrawing iodine atoms, 1,1-difluoro-2,2-diiodoethene exhibits unique chemical properties, making it a valuable intermediate in the synthesis of various organofluorine compounds and pharmaceuticals. It is typically synthesized through the reaction of 1,1-difluoro-2,2-dichloroethene with potassium iodide. However, it should be handled with care due to its potential toxicity and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 683-79-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 683-79:
(5*6)+(4*8)+(3*3)+(2*7)+(1*9)=94
94 % 10 = 4
So 683-79-4 is a valid CAS Registry Number.
