85726-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85726-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,2 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 85726-31:
(7*8)+(6*5)+(5*7)+(4*2)+(3*6)+(2*3)+(1*1)=154
154 % 10 = 4
So 85726-31-4 is a valid CAS Registry Number.

2-Aminopyridines via reaction of pyridine N-oxides and activated isocyanides
Vamos, Mitchell,Cosford, Nicholas D. P.
, p. 2274 - 2280 (2014/04/03)
A practical and efficient method for the synthesis of substituted 2-aminopyridines from pyridine N-oxides is reported. Yields of purified, isolated products of up to 84% are observed for the one-pot, two-step process. The reaction involves an in situ depr
