Check Digit Verification of cas no
The CAS Registry Mumber 643-76-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 643-76:
(5*6)+(4*4)+(3*3)+(2*7)+(1*6)=75
75 % 10 = 5
So 643-76-5 is a valid CAS Registry Number.

Preparation of trifluorovinyl compounds by lithium salt-promoted monoalkylation of tetrafluoroethene
Ohashi, Masato,Kamura, Ryohei,Doi, Ryohei,Ogoshi, Sensuke

Treatment of tetrafluoroethene (TFE) with diethylzinc in the presence of lithium iodide gave 1,1,2-trifluoro-1-butene in moderate yield. In the absence of lithium iodide, however, the nucleophilic addition of diethylzinc to TFE proceeded very slowly to afford ethyl 1,1,2,2-tetrafluorobutylzinc. The addition of lithium iodide to a solution of ethyl-1,1,2,2-tetrafluorobutylzinc resulted in a smooth transformation into 1,1,2-trifluoro-1-butene. In the presence of lithium chloride, the reaction of TFE with benzyl or allyl Grignard reagents afforded the corresponding monosubstituted products in good to excellent yields.
Reaction of fluoro(phenyl)carbene with Schiff bases: Synthesis of 2-fluoro-2-phenylaziridines
Kusei,Novikov,Khlebnikov
, p. 1643 - 1647 (2007/10/03)
Fluoro(phenyl)carbene generated by reaction of α-bromo-α- fluorotoluene with potassium tert-butoxide reacts with Schiff bases to afford the corresponding 2-fluoro-2-phenylaziridines. The latter were isolated in low yields due to their instability under the carbene generation conditions. Although the reaction of α,α-dibromo-α-fluorotoluene with zinc and lead involves formation of fluoro(phenyl)carbene, this procedure is not suitable for the synthesis of 2-fluoro-2-phenylaziridines. 2005 Pleiades Publishing, Inc.
