91971-38-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91971-38-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,7 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91971-38:
(7*9)+(6*1)+(5*9)+(4*7)+(3*1)+(2*3)+(1*8)=159
159 % 10 = 9
So 91971-38-9 is a valid CAS Registry Number.

Acyloxylation of 1,4-Dioxanes and 1,4-Dithianes Catalyzed by a Copper-Iron Mixed Oxide

García-Cabeza, Ana Leticia,Marín-Barrios, Rubén,Moreno-Dorado, F. Javier,Ortega, María J.,Vidal, Hilario,Gatica, José M.,Massanet, Guillermo M.,Guerra, Francisco M.

, p. 6814 - 6821 (2015/10/06)

The use of a copper-iron mixed oxide as a heterogeneous catalyst for the efficient synthesis of α-acyloxy-1,4-dioxanes and 1,4-dithianes employing t-butyl peroxyesters is reported. The preparation and characterization of the catalyst are described. The ef

Bu4NI-catalyzed C-O bond formation by using a cross-dehydrogenative coupling (CDC) reaction

experimental part, p. 4085 - 4089 (2011/05/03)

The creme de la creme! A practical and simple Bu 4NI-catalyzed C-O bond formation was achieved by using a cross-dehydrogenative coupling (CDC) reaction with tert-butyl hydroperoxide (TBHP) as the ultimate oxidant (see scheme; R1=aryl
