90176-78-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90176-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,7 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90176-78:
(7*9)+(6*0)+(5*1)+(4*7)+(3*6)+(2*7)+(1*8)=136
136 % 10 = 6
So 90176-78-6 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.
