Check Digit Verification of cas no
The CAS Registry Mumber 5825-71-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,2 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5825-71:
(6*5)+(5*8)+(4*2)+(3*5)+(2*7)+(1*1)=108
108 % 10 = 8
So 5825-71-8 is a valid CAS Registry Number.

Reactions of 2-X-pyridinium-N-imines (X = F, Cl, Br, CN, OPh, NH2, N-morpholine) with dimethyl acetylenedicarboxylate (DMAD) have been studied. In the case of X = Cl, Br, CN, OPh both 7-substituted- and 7-H-pyrazolo[1,5-a]pyridines are formed. The 7-H/7-X ratio usually increases with the growing solvent polarity. The reaction of N-amino-2-iminopyridine with DMAD gives substituted pyrido[1,2-b][1,2,4]triazine.
