Check Digit Verification of cas no
The CAS Registry Mumber 51209-82-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,2,0 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 51209-82:
(7*5)+(6*1)+(5*2)+(4*0)+(3*9)+(2*8)+(1*2)=96
96 % 10 = 6
So 51209-82-6 is a valid CAS Registry Number.

Reactions of Alkyl-lithium Compounds with Aryl Halides
Huddle, Penelope A.,Perold, Guido W.

Reation of methyl-lithium with tribromophenols and with other aryl polyhalides leads directly to bi- and tri-aryl products. para-Substituents (Y) of 2,6-dibromo-4-Y-phenols promote arylation of substrates by their own lithiation products as Y becomes more electron-withdrawing.An aryne epoxide is not an intermediate in these reactions. 2,4,6-Tribromo-Z-benzenes react to form coupling products when Z can co-ordinate to an introduced ortho-lithium atom or when Z can be directly lithiated.Dimeric aggregation of the organolithium intermediates occurs so as to favor coupling to halogenated substrates.Both polar (ionic) and free-radical pathways are involved.
