71404-76-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71404-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,0 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 71404-76:
(7*7)+(6*1)+(5*4)+(4*0)+(3*4)+(2*7)+(1*6)=107
107 % 10 = 7
So 71404-76-7 is a valid CAS Registry Number.

Ammonium Iodide Catalyzed Selenolactonization of Unsaturated Acids

Shi, Hongwei,Yu, Chen,Zhu, Min,Yan, Jie

, p. 57 - 64 (2016)

A convenient procedure is developed for the preparation of selenolactones from unsaturated acids and diselenides using a catalytic amount of ammonium iodide in combination with m-chloroperoxybenzoic acid as the oxidant. This catalytic ring-closing method

ORGANOSELENIUM-INDUCED CYCLIZATIONS IN ORGANIC SYNTHESIS

Nicolaou, K.C.

, p. 4097 - 4109 (2007/10/02)

A number of organoselenium reagents are introduced as efficient initiators of ring closures leading from unsaturated substrates to lactones, cyclic ethers, cyclic thioethers, N-heterocycles and carbocycles.These cyclizations often proceed with high ring selectivity and stereoselectivity and are accompained by the incorporation of the phenylseleno group (PheSe) into the final product.Methods are described for the effective removal of this group (PheSe) by oxidation or reduction achieving unsaturation or saturation.Finally the successful application of this Se-based methodology to the synthesis of stable and biologically active prostacyclins is outlined.Representative experimental procedures are included.
