Check Digit Verification of cas no

The CAS Registry Mumber 181143-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,1,4 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 181143-79:
(8*1)+(7*8)+(6*1)+(5*1)+(4*4)+(3*3)+(2*7)+(1*9)=123
123 % 10 = 3
So 181143-79-3 is a valid CAS Registry Number.

Silver-Catalyzed One-Pot Three-Component Selective Synthesis of β-Hydroxy Selenides

supporting information, p. 4336 - 4340 (2018/10/15)

A convenient, multi-component reaction of organoboronic acids, selenium powder and epoxides has been developed, providing an efficient protocol for the synthesis of β-hydroxy selenides with excellent selectivity and good functional group tolerance. Preliminary mechanistic studies suggest that the reaction proceeds through the silver-catalyzed radical selenation of the arylboronic acids to generate a diselenide, and subsequent selenium-mediated selective ring-opening arylselenation of epoxides. (Figure presented.).

Paragraph 0135-0138, (2017/03/08)

The invention relates to a synthetic method of Beta-hydroxyl selenide compound. The method includes: in organic solvent, in the presence of catalyst and alkali, allowing halogenated compound to react with elemental Se and epoxy compound to obtain Beta-hydroxyl selenide compound. The synthetic method has the advantages that reaction is simple, operating is simple, yield is high, the method is a novel one, a novel synthetic route is provided for the synthesis of the Beta-hydroxyl selenide compounds, and the method has good scientific research value and industrial potential.

Convenient preparation of ytterbium(III) chalcogenolate complexes by insertion of ytterbium into chalcogen-chalcogen bonds. Application in the ring-opening of epoxides

Dowsland, Jennifer,McKerlie, Fiona,Procter, David J.

, p. 4923 - 4927 (2007/10/03)

Convenient conditions are reported for the preparation of ytterbium(III) chalcogenolate complexes by insertion of ytterbium metal into the chalcogen- chalcogen bond of disulfides, diselenides, and ditellurides. The resulting complexes have been found to t
