134296-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134296-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,9 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134296-74:
(8*1)+(7*3)+(6*4)+(5*2)+(4*9)+(3*6)+(2*7)+(1*4)=135
135 % 10 = 5
So 134296-74-5 is a valid CAS Registry Number.

Halofluorination of Alkenes Using Dilute Hydrofluoric Acid
Kuroboshi, Manabu,Hiyama, Tamejiro
, p. 1799 - 1806 (1995)
Iodofluorination of alkenes was achieved with N-iodosuccinimide, potassium hydrogendifluoride, and 1 M hydrofluoric acid using tetrabutylammonium fluoride as a phase-transfer catalyst.The active fluorinating reagent was shown to be tetrabutylammonium dihy
