34154-31-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34154-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,5 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34154-31:
(7*3)+(6*4)+(5*1)+(4*5)+(3*4)+(2*3)+(1*1)=89
89 % 10 = 9
So 34154-31-9 is a valid CAS Registry Number.

An Alternative Synthesis of 3-Amino-1,2,3,4-tetrahydrocarbazoles

Bird, C. W.,Wee, A. G. H.

, p. 191 - 192 (2007/10/02)

3-Amino-1,2,3,4-tetrahydrocarbazoles are easily prepared from the readily available 3-hydroxy-1,2,3,4-tetrahydrocarbazoles by conversion of the latter to the p-toluene- or methanesulfonate ester, followed by nucleophilic displacement with azide ion.The resulting 3-azido-1,2,3,4-tetrahydrocarbazoles are then catalytically hydrogenated to their 3-amino counterparts.

3-Amido-1,2,3,4-tetrahydrocarbazoles

-

, (2008/06/13)

3-(Substituted-amino)-1,2,3,4-tetrahydrocarbazoles are prepared by reacting appropriate 4-substituted-aminocyclohexanones with a phenylhydrazine, by reacting a 3-(sulfonyloxy)-1,2,3,4-tetrahydrocarbazole with an appropriate substituted amine, or by reduction of an appropriate 3-(acylamino)-1,2,3,4-tetrahydrocarbazole. The 3-(substituted-amino)-1,2,3,4-tetrahydrocarbazoles of this invention have analgetic and psychotropic activities. Moreover, certain of these compounds also have antihistaminic activity.
