Check Digit Verification of cas no

The CAS Registry Mumber 139326-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,2 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139326-89:
(8*1)+(7*3)+(6*9)+(5*3)+(4*2)+(3*6)+(2*8)+(1*9)=149
149 % 10 = 9
So 139326-89-9 is a valid CAS Registry Number.

Solvent reorganisation as the driving force for rate changes of Menschutkin reactions in an ionic liquid

Yau, Hon Man,Howe, Andrew G.,Hook, James M.,Croft, Anna K.,Harper, Jason B.

, p. 3572 - 3575 (2009)

The effect on the rate of reaction of each of a series of Menschutkin processes on changing from a molecular solvent to an ionic liquid was investigated. In each case, the rate acceleration observed at room temperature could be attributed to the change in

EFFECTS OF SUBSTITUENTS IN THE BENZYL BROMIDE ON THE KINETICS OF THE BENZYLATION OF AMINES

Shpan'ko, I. V.,Korostylev, A. P.,Rusu, L. N.

, p. 1715 - 1723 (2007/10/02)

The kinetics of the reactions of 3- and 4-substituted benzyl bromides with amines having various structures in nitrobenzene at 40 deg C were investigated.The 4-substituted benzyl bromides have higher reactivity compared with that calculated on the basis of the linear correlations according to the Hammett-Taft equation for unsubstituted and 3-substituted benzyl bromides containing electron-withdrawning substituents.The reactivity of benzyl bromides containing electron-donating substituents obeys a linear correlation with the ?+ constants.The effects of structural changes in the substrate and the nucleophile on the character of the transition states of the investigated reactions is discussed.
