350-59-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 350-59-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 350-59:
(5*3)+(4*5)+(3*0)+(2*5)+(1*9)=54
54 % 10 = 4
So 350-59-4 is a valid CAS Registry Number.

Chemistry of Halogenoperfluoroalkanes> Synthesis of Fluorinated Ethers and Thioethers via Radical or Anionic Intermediates

Wakselman, Claude,Tordeux, Marc

, p. 4047 - 4051 (2007/10/02)

Condensation of bromotrifluoromethane with potassium thiophenoxides in DMF is performed under pressure (2-3 atm) in a glass apparatus.Inhibition by nitrobenzene shows that a SRN1 mechanism is involved in the formation of aryl trifluoromethyl sulfides.Dichlorodifluoromethane itself reacts through a similar process to give aryl chlorodifluoromethyl sulfides.Condensation of 1,1,2-trichlorotrifluoroethane with potassium thiophenoxide or phenoxide occurs even in the presence of nitrobenzene.The formation of aryl 2,2-dichloro-1,1,2-trifluoroethyl sulfides or ethers can be explained by a chain carbanionic mechanism.
