66443-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66443-85-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,4 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66443-85:
(7*6)+(6*6)+(5*4)+(4*4)+(3*3)+(2*8)+(1*5)=144
144 % 10 = 4
So 66443-85-4 is a valid CAS Registry Number.

Ozonides of perfluorooct-1-ene and perfluorooct-2-ene
Odinokov,Akhmetova,Savchenko,Bazunova,Paramonov,Khalilov
, p. 1103 - 1105 (2007/10/03)
Ozonides of higher perfluoroalkenes were prepared for the first time by ozonation of perfluorooct-1-and -2-enes in Freon-113. The structures of the resulting compounds were confirmed by 13C NMR spectroscopy and GLC-mass spectrometry.
