64764-41-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64764-41-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,6 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 64764-41:
(7*6)+(6*4)+(5*7)+(4*6)+(3*4)+(2*4)+(1*1)=146
146 % 10 = 6
So 64764-41-6 is a valid CAS Registry Number.

Intrinsic Reactivities of Some Carbanions in ?-Adduct Forming Reactions

Crampton, Michael R.,Stevens, Andrew J.

, p. 1715 - 1720 (2007/10/02)

Kinetic and equilibrium data are reported for nucleophilic attack in methanol at unsubstituted ringpositions of 1,3,5-trinitrobenzene, 2,4,6-trinitrotoluene and 1-chloro-2,4,6-trinitrobenzene by carbanions derived from dimethyl malonate, ethyl cyanoacetate and 4-nitro-, 4-cyano- and 2-cyanobenzyl cyanides.The results are used to determine intrinsic reactivities for the carbanions in these ?-adduct forming reactions and are discussed in terms of the electronic and solvent reorganisation occurring during reaction.
