336-50-5 Usage
General Description
1,1,2,2-Tetrachlorotetrafluorocyclobutane is a chlorofluorocarbon compound with the chemical formula C4Cl2F4. It is a colorless, odorous gas that is commonly used as a refrigerant and propellant in aerosol sprays. However, due to its ozone-depleting properties, it has been phased out of use in many countries as part of global efforts to protect the ozone layer. Exposure to 1,1,2,2-tetrachlorotetrafluorocyclobutane can cause irritation to the eyes, skin, and respiratory system, and long-term exposure can have harmful effects on the environment and human health. Therefore, the production and use of this chemical are strictly regulated.
Check Digit Verification of cas no
The CAS Registry Mumber 336-50-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 336-50:
(5*3)+(4*3)+(3*6)+(2*5)+(1*0)=55
55 % 10 = 5
So 336-50-5 is a valid CAS Registry Number.

-Cycloadditions to Strained Bridgehead Olefins. I. 1,1-Dichloro-2,2-difluoroethene
Becker, Konrad B.,Hohermuth, Martin K.
, p. 229 - 234 (1982)
The strained bridgehead olefins bicyclonon-1-ene (1), bicyclonon-1(8)-ene (2), and bicyclonon-1-ene (3) react rapidly with 1,1-dichloro-2,2-difluorethene (5) to yield mixtures of regioisomeric dichlorodifluorocyclobutanes 8/9, 10/11 and 12/13, respectively.On the contrary, the reaction of 5 with the model compound (E)-1-methylcyclooctene (4) is completely regioselective.The structure of the cycloadducts has been elucidated mainly by 19F-NMR. and 13C-NMR. spectroscopy.
