Uses
1H-Pyrrolo[2,3-b]pyridin-4-ol has been used as a high performance polyazaindole as a novel acid fluorescent sensor with a tunable ICT effect. 1H-Pyrrolo[2,3-b]pyridin-4-ol is also used as a reactant in the design and synthesis of potent and selective azaindole-based Rho kinase (ROCK) inhibitors.
Check Digit Verification of cas no
The CAS Registry Mumber 74420-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,2 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74420-02:
(7*7)+(6*4)+(5*4)+(4*2)+(3*0)+(2*0)+(1*2)=103
103 % 10 = 3
So 74420-02-3 is a valid CAS Registry Number.

Concise and Efficient Synthesis of 4-Fluoro-1H-pyrrolo[2,3-b]pyridine
Thibault, Carl,L'Heureux, Alexandre,Bhide, Rajeev S.,Ruel, Rejean
, p. 5023 - 5025 (2007/10/03)
(Equation presented) Two routes describing the preparation of 4-fluoro-1H-pyrrolo[2,3-b]pyridine (4a) from 1H-pyrrolo[2,3-b]pyridine N-oxide (1) are presented. Regioselective fluorination was achieved using either the Balz-Schiemann reaction or lithium-halogen exchange.
