139099-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139099-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,9 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139099-74:
(8*1)+(7*3)+(6*9)+(5*0)+(4*9)+(3*9)+(2*7)+(1*4)=164
164 % 10 = 4
So 139099-74-4 is a valid CAS Registry Number.

On the Preparation of the Sulfurane Adducts CF3S(O)F*MF5 (M = As, Sb) and (CF3)2SO*SbF5
Minkwitz, Rolf,Molsbeck, Walter
, p. 1733 - 1735 (2007/10/02)
Preparation, Raman Spectra, NMR SpectraThe adducts CF3S(O)F*MF5 (M = As, Sb) and (CF3)2SO*SbF5 have been prepared by reaction of the sulfuranes CF3S(O)F and (CF3)2SO with AsF5 and SbF5 in liquid HF, and characterized by Raman and 19F NMR spectroscopy.
