Check Digit Verification of cas no
The CAS Registry Mumber 343222-12-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,2,2 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 343222-12:
(8*3)+(7*4)+(6*3)+(5*2)+(4*2)+(3*2)+(2*1)+(1*2)=98
98 % 10 = 8
So 343222-12-8 is a valid CAS Registry Number.

ADDITION DE PHENYLHYDRAZONES AUX OLEFINES EN MILIEU NEUTRE
Fevre, G. Le,Hamelin, J.
, p. 887 - 891 (2007/10/02)
Phenylhydrazones may exhibit three types of reactivity towards alkenes: nucleophilic attack by carbon, nucleophilic attack by nitrogen and 1,3-dipolar cycloaddition through the azomethine imine ylide.The course of the reaction depends on the nature of the hydrazone and alkene substituents.
