Check Digit Verification of cas no

The CAS Registry Mumber 137279-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,7 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137279-24:
(8*1)+(7*3)+(6*7)+(5*2)+(4*7)+(3*9)+(2*2)+(1*4)=144
144 % 10 = 4
So 137279-24-4 is a valid CAS Registry Number.

Alkylation of Cycloalkanoindoles via Indolylmagnesium Salts: Synthesis of 3H-Indoles and Oxidative Rearrangement to Spiro-3'-ones

Rodriguez, Jose-Gonzalo,Andres, Angel San

, p. 1293 - 1299 (2007/10/02)

Alkylation of cycloalkanoindolylmagnesium iodide with alkyl halides has been analyzed to prepare cycloalkano-3H-indoles, methyl and N,N-dimethylpropyl derivatives.Spiro derivatives appear as secondary products in this reaction.Selectivity and optimization of the reaction has been determined and a mechanism for the formation of the spiro derivative is proposed.
