69367-66-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69367-66-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,3,6 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 69367-66:
(7*6)+(6*9)+(5*3)+(4*6)+(3*7)+(2*6)+(1*6)=174
174 % 10 = 4
So 69367-66-4 is a valid CAS Registry Number.

, p. 1 - 10 (2007/10/02)
In concentrations larger than 1 M triphenyl carbenium ions associate in trifluoroacetic acid in spite of their coulombic repulsion.This phenomenon depends extremely strong on concentration.Astonishingly a separate NMR signal is found for the aggregate whe
