61098-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61098-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,0,9 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 61098-01:
(7*6)+(6*1)+(5*0)+(4*9)+(3*8)+(2*0)+(1*1)=109
109 % 10 = 9
So 61098-01-9 is a valid CAS Registry Number.

Photolysis of perfluoroacyl fluorides
Tonelli, Claudio,Tortelli, Vito
, p. 117 - 123 (2007/10/03)
The photochemical decarbonylation and coupling of acyl fluorides containing perfluoroalkyl and perfluoro(oxa)alkyl chains have been re-examined. The reaction on either single acyl fluorides or on their binary mixtures has allowed the formation and isolation of macromolecular perfluoro(oxa)alkanes having interesting physical-chemical properties. These perfluoropolyethers are also useful as model compounds and standards to better characterize more complex mixtures of similar commercial products.
