5960-22-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5960-22-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,6 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5960-22:
(6*5)+(5*9)+(4*6)+(3*0)+(2*2)+(1*2)=105
105 % 10 = 5
So 5960-22-5 is a valid CAS Registry Number.

KINETICS OF FORMATION OF SOME NEW HETEROCYCLIC AZOMETHINES DERIVED FROM NITROSO AND ACTIVE METHYL COMPOUNDS

Mahmoud, Mohamed Rafat,El-Samahy, Ahmed Abdalla,Hamed, Maher Mohamed Ahmed,Shaker, Ali Mohamed

, p. 217 - 222 (2007/10/02)

The kinetics of base-catalysed condensation of active methyl heterocyclic quaternary salts with some nitroso derivatives in methanol have been investigated.In the presence of piperidine, the reaction was found to follow pseudo-second-order kinetics, being first order with respect to each of the reactants.It is suggested that dehydration of the carbinolamine intermediate is the rate determining step.This is supported by the observation that the reaction rate increases as the electron releasing power of the substituent attached to the nitroso aromatic ring is increased or as the electron withdrawing power of the heterocyclic moiety attached to the active methyl group is increased.Furthermore, it is concluded that the tendency of the hydroxylic solvent employed as a reaction medium to associate through hydrogen bonding plays an important role in the condensation rate.
