Check Digit Verification of cas no

The CAS Registry Mumber 128408-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,0 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128408-39:
(8*1)+(7*2)+(6*8)+(5*4)+(4*0)+(3*8)+(2*3)+(1*9)=129
129 % 10 = 9
So 128408-39-9 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 (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.
