130755-47-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130755-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,5 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130755-47:
(8*1)+(7*3)+(6*0)+(5*7)+(4*5)+(3*5)+(2*4)+(1*7)=114
114 % 10 = 4
So 130755-47-4 is a valid CAS Registry Number.

Microwave-assisted aliphatic fluorine-chlorine exchange using triethylamine trihydrofluoride (TREAT-HF)

Kremsner, Jennifer M.,Rack, Michael,Pilger, Christian,Oliver Kappe

, p. 3665 - 3668 (2009)

Aliphatic fluorine-chlorine exchange reactions can be performed under microwave conditions using TREAT-HF as a mild and selective fluorination reagent. The highly polar TREAT-HF couples efficiently with microwave irradiation and reaction temperatures of 250 °C can be reached within 30 s. Under these conditions dichloromethyl- and trichloromethyl substrates can be converted into the corresponding fluoro analogs within 5 min. In order to prevent corrosion of borosilicate reaction vessel at high temperatures the use of sintered silicon carbide microwave vials is introduced.

Process for the preparation of perhaloalkylthioethers

-

, (2008/06/13)

The present invention relates to a process for the preparation of perhaloalkylthioethers by bringing a perhaloalkyl halide, preferably a bromide or an iodide, into contact with a disulphide in the presence of zinc and of sulphur dioxide or of a dithionite or of a hydroxymethanesulphinate or of a formate anion and sulphur dioxide.
