Check Digit Verification of cas no
The CAS Registry Mumber 3739-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,3 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3739-81:
(6*3)+(5*7)+(4*3)+(3*9)+(2*8)+(1*1)=109
109 % 10 = 9
So 3739-81-9 is a valid CAS Registry Number.

The first and facile synthesis of N,N′-dialkylated 2,6,9-triazabicyclo[3.3.1]nonadienes was achieved by the [4 + 4] self-condensation of β-formyl-β-nitroenamine in the presence of ammonium acetate. The 2,6- A nd 2,9-dialkylated products were found to be interconvertible when dissolved in a solvent. This isomerization proceeds through intramolecular ring transformation via a common intermediate under equilibrium. This journal is
Formylnitroenamines: Useful building blocks for nitrated pyridones and aminopyridines with functional groups

experimental part, p. 325 - 334 (2009/03/12)
β-Formyl-β-nitroenamines 1 possess both an electrophilic formyl group and a nucleophilic amino group and, therefore, serve as C3N1 building blocks having a nitro group to afford nitropyridones and aminonitropyridines with a functional group at the 3-posit
