25796-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25796-89-8 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 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25796-89:
(7*2)+(6*5)+(5*7)+(4*9)+(3*6)+(2*8)+(1*9)=158
158 % 10 = 8
So 25796-89-8 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 (1998)

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

Palladium-catalyzed synthesis of 2,3-disubstituted 5-azaindoles via heteroannulation reaction and of 2-substituted 5-azaindoles through domino sila-Sonogashira/5-endo cyclization

Livecchi, Marion,Calvet, Geraldine,Schmidt, Frederic

, p. 5006 - 5016 (2012/07/03)

A general and efficient procedure for the synthesis of 2,3-disubstituted 5-azaindoles through the palladium-catalyzed heteroannulation of 4-acetamido-3-iodopyridines and diaryl-, dialkyl-, or arylalkylalkynes is described along with a study of the reactio
