126199-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126199-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,1,9 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 126199-99:
(8*1)+(7*2)+(6*6)+(5*1)+(4*9)+(3*9)+(2*9)+(1*9)=153
153 % 10 = 3
So 126199-99-3 is a valid CAS Registry Number.

METALATION OF 1,4-DIHYDROPYRIDINE ESTERS
Poindexter, Graham S.,Foley, Michael A.,Licause, Joseph F.
, p. 3393 - 3396 (2007/10/02)
4-Aryl-1,4-dihydro-2,6-dimethyl-3,5-pyridinedicarboxylic esters are metalated at the NH and the C-2 methyl positions via treatment with two equivalents of n-butyl lithium.The resulting dilithio species can be treated with a variety of electrophiles to fur
