1670-83-3 Usage

Uses

Indole-7-carboxylic acid is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff fields.

Check Digit Verification of cas no

The CAS Registry Mumber 1670-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1670-83:
(6*1)+(5*6)+(4*7)+(3*0)+(2*8)+(1*3)=83
83 % 10 = 3
So 1670-83-3 is a valid CAS Registry Number.

Palladium-Catalyzed Carbonylation of Haloindoles: No Need for Protecting Groups

Kumar, Kamal,Zapf, Alexander,Michalik, Dirk,Tillack, Annegret,Heinrich, Timo,Boettcher, Henning,Arlt, Michael,Beller, Matthias

, p. 7 - 10 (2004)

(Equation presented) For the first time, palladium-catalyzed carbonylations of unprotected bromoindoles have been performed successfully with different N- and 0-nucleophiles. Various indole carboxylic acid derivatives are accessible in excellent yield. For example, aminocarbonylation of 4-, 5-, 6-, or 7-bromoindole with arylethylpiperazines provides a direct one-step synthesis for CNS active amphetamine derivatives.

NEW SYNTHESIS OF INDOLE-7-CARBOXYLIC ACID

Dulenko, V. I.,Nikolyukin, Yu. A.

, p. 36 - 37 (1986)

A new preparative method for synthesis of indole-7-carboxylic acid has been developed, consisting in reductive cyclization of β-(dimethylamino)-3-carbomethoxy-2-nitrostyrene by the action of iron in acetic acid.
