Check Digit Verification of cas no
The CAS Registry Mumber 123506-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,5,0 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123506-67:
(8*1)+(7*2)+(6*3)+(5*5)+(4*0)+(3*6)+(2*6)+(1*7)=102
102 % 10 = 2
So 123506-67-2 is a valid CAS Registry Number.

Lithiation of Methoxypyridines Directed by α-Amino Alkoxides
Comins, Daniel L.,Killpack, Michael O.
, p. 69 - 73 (2007/10/02)
The addition of methoxypyridinecarboxaldehydes to certain lithium dialkylamides gave α-amino alkoxides in situ that were ring-lithiated with alkyllithium bases.Alkylation and hydrolysis on workup provided ring-substituted methoxypyridinecarboxaldehydes via a one-pot reaction.The one-pot methylation of isomeric methoxypyridinecarboxaldehydes was examined.The regioselectivity of the lithiation-methylation was dependent on the aldehyde, the amine component of the α-amino alkoxide, and the metalation conditions.When lithiated N,N,N'-trimethylethylenediamine was used as the amine component of the α-amino alkoxide, methylation generally occured ortho to the aldehyde function.The analogous reactions using lithium N-methylpiperazide as the amine component gave substitution next to the methoxy group.Several new methylated methoxypyridinecarboxaldehydes were prepared in a regioselective manner by using this one-pot procedure.
