1428156-48-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428156-48-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,1,5 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1428156-48:
(9*1)+(8*4)+(7*2)+(6*8)+(5*1)+(4*5)+(3*6)+(2*4)+(1*8)=162
162 % 10 = 2
So 1428156-48-2 is a valid CAS Registry Number.

Regioselective C2-arylation of imidazo[4,5-b]pyridines
Macdonald, Jonathan,Oldfield, Victoria,Bavetsias, Vassilios,Blagg, Julian
, p. 2335 - 2347 (2013/04/23)
We show that N3-MEM-protected imidazo[4,5-b]pyridines undergo efficient C2-functionalisation via direct C-H arylation. Twenty-two substituted imidazo[4,5-b]pyridines are prepared and iterative, selective elaboration of functionalised imidazo[4,5-b]pyridin
