18024-11-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18024-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,2 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18024-11:
(7*1)+(6*8)+(5*0)+(4*2)+(3*4)+(2*1)+(1*1)=78
78 % 10 = 8
So 18024-11-8 is a valid CAS Registry Number.

Solvent-free solid acid-catalyzed electrophilic annelations: A new green approach for the synthesis of substituted five-membered N-heterocycles

Abid, Mohammed,Spaeth, Andrew,Toeroek, Bela

, p. 2191 - 2196 (2006)

An effective microwave-induced, solid acid-catalyzed, environmentally benign synthesis of substituted pyrroles, indoles and carbazoles under solvent-free conditions is described. The new synthetic methodology is based on the use of a considerably strong solid acid, K-10 montmorillonite. Both the cyclialkylation of amines and annelation of pyrroles and indoles have been completed within minutes and provided excellent (75-98%) yields with practically 100% selectivity.

Modifications to the Vilsmeier-Haack formylation of 1,4-dimethylcarbazole and its application to the synthesis of ellipticines

Deane, Fiona M.,Miller, Charlotte M.,Maguire, Anita R.,McCarthy, Florence O.

experimental part, p. 814 - 823 (2011/10/04)

Figure represented. An improved method for the preparation of 3-formyl-1,4-dimethylcarbazole, a key intermediate in the synthesis of ellipticine, is presented. Conditions of the Vilsmeier-Haack reaction have been modified to facilitate the production of 3-formyl-1,4-dimethylcarbazole as a major product leading to an overall improvement in yield of ellipticine from 3% to 14%. This approach was also applied to the synthesis of 6-methylellipticine and 9-methoxyellipticine.
