25797-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25797-08-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,9 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25797-08:
(7*2)+(6*5)+(5*7)+(4*9)+(3*7)+(2*0)+(1*8)=144
144 % 10 = 4
So 25797-08-4 is a valid CAS Registry Number.

Synthesis of 5-, 6- and 7-azaindoles via palladium-catalyzed heteroannulation of internal alkynes
Ujjainwalla, Feroze,Warner, Daniel
, p. 5355 - 5358 (2007/10/03)
The palladium-catalyzed heteroannulation of internal alkynes using orthoaminoiodopyridine derivatives is described. This experimentally simple procedure, which employs a Pd(dppf)Cl2/LiCl/Na2CO3 reagent system, allows rapid
