670225-79-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 670225-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,0,2,2 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 670225-79:
(8*6)+(7*7)+(6*0)+(5*2)+(4*2)+(3*5)+(2*7)+(1*9)=153
153 % 10 = 3
So 670225-79-3 is a valid CAS Registry Number.

α-Fluorocarbonyl compounds by isomerization of 2-fluorooxiranes
Michel,Schlosser
, p. 2429 - 2434 (2007/10/03)
2-Fluorooxiranes 2 can be isolated after peracid oxidation of fluoroalkenes 1. When treated with the triethylamine hydrogen fluoride adduct, the intermediates 2 isomerize to afford α-fluorinated carbonyl compounds 3.
