379-30-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 379-30-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 379-30:
(5*3)+(4*7)+(3*9)+(2*3)+(1*0)=76
76 % 10 = 6
So 379-30-6 is a valid CAS Registry Number.

The Effect of Both ?-Donor Substituents and Acid Media on the Formation of Trityl Cations, Studied by Relaxation Methods and NMR-Spectroscopy

Blumenstock, H.,Dickert, F.,Fackler, H.,Hammerschmidt, A.

, p. 157 - 170 (2007/10/02)

Trityl trifluoroacetates were taken to study why ion formation from ionogens is favoured by acid media.From relaxation measurements, NMR-spectroscopy and conductivity studies it was found that this effect is due to anion solvation by acid, namely a specific solvation of the free anions and a statistical solvation of the anions bound in the ionogen.This leads to a drastically reduced ion recombination rate constant even at low concentrations of acid and an increased dissociation rate constant at rather high concentrations of acid. -.Keywords: Kinetics/ Ion solvation/ Carbenium ions/ NMR-spectroscopy
