3932-66-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3932-66-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,3 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3932-66:
(6*3)+(5*9)+(4*3)+(3*2)+(2*6)+(1*6)=99
99 % 10 = 9
So 3932-66-9 is a valid CAS Registry Number.

2,3,3-Trifluoro-1-cyclobutene and Dimers of 1,1,2-Trifluoro-1,3-butadiene from Tetrafluoroethylene-Vinylsilane Cycloadducts

England, David C.,Weigert, Frank J.,Calabrese, Joseph C.

, p. 4816 - 4819 (2007/10/02)

(Tetrafluorocyclobutyl)silanes prepared by thermal cycloaddition of tetrafluoroethylene (TFE) to vinylsilanes were pyrolyzed at 600 deg C to give mixtures containing dimers of 1,1,2-trifluoro-1,3-butadiene.The monomeric diene 1 was undoubtly an intermediate formed by ring opening of initially formed 2,3,3-trifluoro-1-cyclobutene (9).This cyclobutene has been prepared by fluoride ion catalyzed removal of trimethylfluorosilane from (2,2,3,3-tetrafluorocyclobutyl)trimethylsilane (8) at room temperature.One of the dimers of the diene was saturated and was shown by X-raycrystallography to have the tricyclooctane structure (3) corresponding to a previously reported structure for a perfluorobutadiene dimer.The cyclooctadiene 2 presumed to be the precursor to dimer 3 and Diels-Alder dimers (vinylcyclohexenes) 4 and 7 were characterized by 19F NMR analyses of liquid fractions.
