Check Digit Verification of cas no
The CAS Registry Mumber 100921-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,2 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 100921-66:
(8*1)+(7*0)+(6*0)+(5*9)+(4*2)+(3*1)+(2*6)+(1*6)=82
82 % 10 = 2
So 100921-66-2 is a valid CAS Registry Number.

ACTION DU N-BUTYLLITHIUM SUR LES BROMO-3 HALOGENO-2 PYRIDINES FLUOREE, CHLOREE ET BROMEE PRINCIPE ET ETUDE D'UNE POSSIBILITE REACTIONNELLE NOUVELLE: L'HOMOTRANSMETALLATION

Apart from the common bromine-lithium exchange reaction in brominated aromatic compounds, it is possible to obtain a lithio-derivative quite different from the one usually described in such a reaction.This new reaction, which results from a special experimental condition is called 'homotransmetalation', and it occurs when using n-buthyllithium and 3-bromo 2-halogenopyridines (1).Different behaviour is observed with the three similar compounds (1:X = F,Cl,Br).Explanations are proposed of these results.It is then possible to compare the relative stabilities of the proposed lithio-structures.It is evident that nucleophilic substitution of bromine in position 4 of the pyridine ring is easier than is usually recognised.
