104283-72-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 104283-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,8 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104283-72:
(8*1)+(7*0)+(6*4)+(5*2)+(4*8)+(3*3)+(2*7)+(1*2)=99
99 % 10 = 9
So 104283-72-9 is a valid CAS Registry Number.

Directed functionalization of halophenyl-2-oxazolines with TMPMgCl?LiCl

Batista, Joo H. C.,Santos, Fernanda M. Dos,Bozzini, Leandro A.,Vessecchi, Ricardo,Oliveira, Alfredo R. M.,Clososki, Giuliano C.

, p. 967 - 977 (2015/02/19)

A variety of difunctionalized aryl-2-oxazolines were prepared from the reaction of halophenyl-2-oxazolines and TMPMgCl?LiCl to give an organomagnesium reagent, which was then treated with various electrophiles. The metalation step takes place under mild conditions, and this process al-lows for the isolation of the desired products in good yields. No isomeric or other benzyne-derived products were detected. The influence of the halogen substituents on the acidity of the aromatic hydrogen atoms was evaluated by using density functional theory (DFT) calculations.
