6940-11-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6940-11-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,4 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6940-11:
(6*6)+(5*9)+(4*4)+(3*0)+(2*1)+(1*1)=100
100 % 10 = 0
So 6940-11-0 is a valid CAS Registry Number.

Polycyclic N-Hetero Compounds. XXII. . Reaction of Pyridine N-oxides and Pyrazino Di-N-Oxides with Formamide
Hirota, Takashi,Namba, Tetsuto,Sasaki, Kenji
, p. 949 - 953 (2007/10/02)
Reactions of pyridine N-oxides, pyrazine N-oxides and their benzologues with formamide are described.Carbamoylation mainly occured at aromatic ring with loss of the N-oxide oxygen atom, however, 2,4,6-trimethylpyridine 1-oxide gave 2- and 4-pyrimidinyl derivatives.
