1240979-09-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1240979-09-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,9,7 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1240979-09:
(9*1)+(8*2)+(7*4)+(6*0)+(5*9)+(4*7)+(3*9)+(2*0)+(1*9)=162
162 % 10 = 2
So 1240979-09-2 is a valid CAS Registry Number.

Utilization of Copper-Catalyzed Carboarylation-Ring Closure for the Synthesis of New Oxazoline Derivatives

Sinai, ádám,Vangel, Dóra,Gáti, Tamás,Bombicz, Petra,Novák, Zoltán

, p. 4136 - 4139 (2015/09/15)

A copper-catalyzed carboarylation-ring-closure strategy was used for the modular synthesis of oxazolines via the reaction of 1-aryl- and 1-alkylpropargylamides and diaryliodonium salts. The novel approach enables the efficient, modular synthesis of oxazol

Gold-catalyzed cyclization of nonterminal propargylic amides to substituted alkylideneoxazolines and-oxazines

Hashmi, A. Stephen K.,Schuster, Andreas M.,Schmuck, Martin,Rominger, Frank

supporting information; experimental part, p. 4595 - 4602 (2011/10/03)

The substrate scope of the gold-catalyzed cyclization of nonterminal propargylic amides to oxazolines and oxazines was investigated. Sixteen alkyl-substituted and 35 aryl-substited substrates were prepared by a very variable route from trimethylsilyl-(TMS
