191402-55-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191402-55-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,4,0 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 191402-55:
(8*1)+(7*9)+(6*1)+(5*4)+(4*0)+(3*2)+(2*5)+(1*5)=118
118 % 10 = 8
So 191402-55-8 is a valid CAS Registry Number.

Gas phase substituent effects. Stabilities of 1-aryl-2,2,2-trifluoroethyl cations
Hishima, Masaaki,Inoue, Hiroki,Fujio, Mizue,Tsuno, Yuho
, p. 685 - 688 (1990)
Gas-phase stabilities of 1-aryl-2,2,2-trifluoroethyl cations were determined based on chloride-transfer equilibria. The substituent effect was analyzed based on the LArSR Eq., giving a remarkably high r of 1.53 and a ρ of -14.6.
