Check Digit Verification of cas no

The CAS Registry Mumber 111323-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,3,2 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 111323-52:
(8*1)+(7*1)+(6*1)+(5*3)+(4*2)+(3*3)+(2*5)+(1*2)=65
65 % 10 = 5
So 111323-52-5 is a valid CAS Registry Number.

Reactions of N-(Arylsulfonoxy)-N-benzylmethylamines with Sodium Methoxide in Methanol

Cho, Bong Rae,Pyun, Sang Yong,Kim, Tae Rin

, p. 8041 - 8044 (2007/10/02)

Reactions of N-(arylsulfonoxy)-N-benzylmethylamines (1) with MeONa in MeOH have been investigated.The eliminations are quantitative, producing only benzylidenemethylamines.The reactions are first order in substrate and first order in base, and an E2 mechanism is evident.Comparison of the rate data reveals that the arenesulfonates are better leaving groups than halogens in imine-forming elimination.For elimination from 1, ρ = 1.14, kH?kD = 3.6, ρlg = 1.30, and β1g = -0.43 have been calculated.Differences in the transition-sate characters for imine-forming eliminations from ArCH2N(Cl)CH3 and 1 have been intepreted in terms of changes in the leaving-group properties and base strength.
