191402-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191402-51-4 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 191402-51:
(8*1)+(7*9)+(6*1)+(5*4)+(4*0)+(3*2)+(2*5)+(1*1)=114
114 % 10 = 4
So 191402-51-4 is a valid CAS Registry Number.

, p. 685 - 688 (2007/10/02)
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.
