344869-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344869-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,8,6 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 344869-12:
(8*3)+(7*4)+(6*4)+(5*8)+(4*6)+(3*9)+(2*1)+(1*2)=171
171 % 10 = 1
So 344869-12-1 is a valid CAS Registry Number.

5,6-CONDENSED 3-NITROPYRIDINES FROM HETEROCYCLIC AMINES AND NITROMALONALDEHYDE
Schaefer, H.,Gewald, K.,Schmidt, M.
, p. 1163 - 1166 (2007/10/02)
The reaction of nitromalonaldehyde with 2-aminothiophenes leads to 5-nitrothienopyridines.The analogous reaction with 3-aminopyrroles leads to 6-nitropyrrolopyridines.The analogous reaction with 4- and 5-aminopyrazoles leads to 6-nitropyrazo
