146253-19-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 146253-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,2,5 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 146253-19:
(8*1)+(7*4)+(6*6)+(5*2)+(4*5)+(3*3)+(2*1)+(1*9)=122
122 % 10 = 2
So 146253-19-2 is a valid CAS Registry Number.

Nucleophilic Amination of Methoxy Arenes Promoted by a Sodium Hydride/Iodide Composite

Kaga, Atsushi,Hayashi, Hirohito,Hakamata, Hiroyuki,Oi, Miku,Uchiyama, Masanobu,Takita, Ryo,Chiba, Shunsuke

, p. 11807 - 11811 (2017/09/20)

A method for the nucleophilic amination of methoxy arenes was established by using sodium hydride (NaH) in the presence of lithium iodide (LiI). This method offers an efficient route to benzannulated nitrogen heterocycles. Mechanistic studies showed that the reaction proceeds through an unusual concerted nucleophilic aromatic substitution.

Tandem phenolic oxidative amidation-intramolecular diels-alder reaction: An approach to the himandrine core

Liang, Huan,Ciufolini, Marco A.

supporting information; experimental part, p. 1760 - 1763 (2010/10/21)

An oxidative cyclization of dienic sulfonamides mediated by iodobenzene diacetate in TFA, followed by a tandem intramolecular Diels-Alder reaction, achieves desymmetrization of a "locally symmetrical" dienone with good levels of diastereoselectivity and leads to valuable synthetic intermediates for the himandrine alkaloids.
