115177-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115177-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,1,7 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 115177-92:
(8*1)+(7*1)+(6*5)+(5*1)+(4*7)+(3*7)+(2*9)+(1*2)=119
119 % 10 = 9
So 115177-92-9 is a valid CAS Registry Number.

RING LITHIATION OF PYRIDONES
Meghani, Premji,Joule, John A.
, p. 1 - 8 (2007/10/02)
Lithiation of 1-methyl-2-pyridone takes place mainly at the methyl group which then leads to a dimer (11) by addition to a second mol equivalent of pyridone at C-6.Lithiation of 1-methyl-4-pyridone takes place cleanly and efficiently at C-2; this lithio d
