53676-44-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53676-44-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,6,7 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53676-44:
(7*5)+(6*3)+(5*6)+(4*7)+(3*6)+(2*4)+(1*4)=141
141 % 10 = 1
So 53676-44-1 is a valid CAS Registry Number.

A SIMPLE ROUTE TO INDOLE-2,3-QUINODIMETHANE-A FACILE SYNTHESIS OF CARBAZOLES

Saroja, B.,Srinivasan, P. C.

, p. 5429 - 5430 (1984)

2,3-Dimethylindole is easily converted into N-benzoyl-2,3-dibromo methylindole, the latter upon treatment with sodium iodide in DMF in the presence of a suitable dienophile furnishes a carbazole derivative.

A new approach to 3-substituted tetrahydro-β-carboline derivative via diethyl acetamidomalonate

Kotha, Sambasivarao,Misra, Shilpi,Mobin, Shaikh M.

scheme or table, p. 933 - 936 (2012/03/22)

Strategically a new approach for the synthesis tetrahydro-β-carboline unit with the aid of diethyl acetamidomalonate as a glycine equivalent has been described. Springer-Verlag 2010.

Acylation, cyanoethylation and alkylation of methyl and phenyl indolylmagnesium salts: Influence of the substituents on the C- and N- reaction products

Rodriguez, J. Gonzalo,Urrutia, Anahi

, p. 129 - 135 (2007/10/03)

Analysis of the influence of the substitution on indolylmagnesium salts in the reaction with benzoyl chloride, acrylonitrile and methyl iodide, giving the C- and N-derivatives, have been carried out. The yield in the C- and N-product depends upon the electronic character and position of the substituent (methyl or phenyl) on the indole ring and of the ethereal solvent as well as the concentration and molar ratio of the reagents. The 2- or 3- phenyl substituted indolylmagnesium salts with acrylonitrile always gave the 1-(2-cyanoethyl)indole derivative.
