Check Digit Verification of cas no
The CAS Registry Mumber 344874-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,8,7 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 344874-67:
(8*3)+(7*4)+(6*4)+(5*8)+(4*7)+(3*4)+(2*6)+(1*7)=175
175 % 10 = 5
So 344874-67-5 is a valid CAS Registry Number.

ELECTRONIC EFFECTS ON CARBON-CHLORINE BONDS
Warnhoff, E. W.,Nakamura, Akira
, p. 503 - 506 (2007/10/02)
For the first time a reaction has been found to study electronic effects on C-Cl bonds in an equilibrium situation.The reaction, the α α' rearrangement of α-chlorodibenzyl ketones, correlates well with the difference in Taft ? deg values with ρ +0.75.
