4H/5H-3,3,4,5,6,6-Hexafluor-cyclohexen is a cyclic organic compound with the molecular formula C6H4F6. It features a six-membered carbon ring with alternating double and single bonds, known as an ene. The compound is characterized by the presence of six fluorine atoms, which are attached to three adjacent carbon atoms in the ring structure. This results in a highly electronegative and reactive molecule. Due to its unique structure and properties, 4H/5H-3,3,4,5,6,6-Hexafluor-cyclohexen has potential applications in various fields, such as pharmaceuticals, materials science, and chemical synthesis, where its fluorinated nature can impart specific reactivity or stability to the compounds in which it is incorporated.

Check Digit Verification of cas no

The CAS Registry Mumber 703-16-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,0 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 703-16:
(5*7)+(4*0)+(3*3)+(2*1)+(1*6)=52
52 % 10 = 2
So 703-16-2 is a valid CAS Registry Number.

Trifluoromethanesulfonic acid: A novel solvent for the electrophilic fluorination of fluoroaromatics

Coe, Paul L.,Stuart, Alison M.,Moody, David J.

, p. 1807 - 1811 (2007/10/03)

Trifluoromethanesulfonic acid has been discovered to be an excellent new solvent for promoting the direct elemental fluorination of aromatics. Fluorobenzene has been successfully fluorinated to a mixture of 1,4-difluorobenzene (31%) and 1,2-difluorobenzene (7%) in CFCl3-CF3SO3H (5%), but no further improvement is observed by the addition of boron trifluoride. When the reaction is carried out in only CFCl3, the main reaction pathway is the 1,2- and 1,4-addition of fluorine to fluorobenzene forming cyclohexenes of molecular formula C6H5F5, and only a small amount of 1,4-difluorobenzene is produced. Although both 1,2- and 1,3-difluorobenzene are fluorinated to 1,2,4-trifluorobenzene in CFCl3-CF3SO3H (10%), 1,4-difluorobenzene does not undergo the same electrophilic substitution reaction.
