23002-14-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23002-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,0 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23002-14:
(7*2)+(6*3)+(5*0)+(4*0)+(3*2)+(2*1)+(1*4)=44
44 % 10 = 4
So 23002-14-4 is a valid CAS Registry Number.

A free radical cascade cyclization of isocyanides with simple alkanes and alcohols

Li, Zejiang,Fan, Fenghua,Yang, Jie,Liu, Zhong-Quan

supporting information, p. 3396 - 3399 (2014/07/08)

A copper-catalyzed free-radical cascade cyclization of isocyanides with simple alkanes and alcohols was developed, which allowed convenient access to various alkyl-substituted phenanthridines.

Electron-transfer-mediated synthesis of phenanthridines by intramolecular arylation of anions from n-(ortho-Halobenzyl)arylamines: regiochemical and mechanistic analysis

Buden, Maria E.,Dorn, Viviana B.,Gamba, Martina,Pierini, Adriana B.,Rossi, Roberto A.

experimental part, p. 2206 - 2218 (2010/06/17)

The synthesis of a series of substituted phenanthridines by photostimulated C-C cyclization of anions from N-(orrAo-halobenzyl)arylamines has been found to proceed in very good to excellent yields (79-95%) in liquid ammonia and in DMSO. The N-(ortho-halobenzyl)arylamines are obtained in good to very good isolated yields (44-85%) by nucleophilic substitution of orthohalobenzylchlorides with different arylamines. The reaction of the anions of a diverse set N-(orthohalobenzyl)arylamines was studied, and the methodology was extended to the synthesis of trispheridine, a natural product, in very good yield, In order to explain the regiochemical outcome of these reactions, a theoretical analysis was performed with DFT methods and the B3LYP functional.
