117573-59-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 117573-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,7 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117573-59:
(8*1)+(7*1)+(6*7)+(5*5)+(4*7)+(3*3)+(2*5)+(1*9)=138
138 % 10 = 8
So 117573-59-8 is a valid CAS Registry Number.

A reliable one-pot synthesis of aryl azides from aryl amines using organotin azides as effective and recoverable reagents

Godoy Prieto, Leonela,Lo Fiego, Marcos J.,Chopa, Alicia B.,Lockhart, María T.

supporting information, p. 26 - 32 (2016/12/18)

A mild and mass-efficient procedure based on the one-pot diazotization-azidodediazoniation of aromatic amines is described. A wide range of aryl azides are obtained in moderate to high yields by using tributyltin azide as an effective and reusable azide source in the presence of p-toluenesulfonic acid at room temperature. The method was also successfully applied employing an insoluble polymer-supported organotin azide.

Efficient conversion of aromatic amines into azides: A one-pot synthesis of triazole linkages

Barral, Karine,Moorhouse, Adam D.,Moses, John E.

, p. 1809 - 1811 (2008/02/02)

An efficient and improved procedure for the preparation of aromatic azides and their application in the Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition ("click reaction") is described. The synthesis of aromatic azides from the corresponding amies i
