98750-90-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 98750-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,5 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98750-90:
(7*9)+(6*8)+(5*7)+(4*5)+(3*0)+(2*9)+(1*0)=184
184 % 10 = 4
So 98750-90-4 is a valid CAS Registry Number.

Synthesis of Selenones: A Comparative Study

Krief, Alain,Dumont, Willy,Denis, Jean-Noel,Evrard, Guy,Norberg, Bernadette

, p. 569 - 570 (1985)

The propensity of several reagents to oxidize selenides to selenones has been evalueted; the scope and limitations of the methods are presented.

Corey-Chaykovsky Cyclopropanation of Nitronaphthalenes: Access to Benzonorcaradienes and Related Systems

Antoniak, Damian,Barbasiewicz, Micha?

, p. 9320 - 9325 (2019/11/19)

Nitronaphthalene derivatives react as Michael acceptors in the Corey-Chaykovsky reaction with alkyl phenyl selenones and alkyl diphenyl sulfonium salts. Mechanistic studies reveal that sterically demanding substituents at the carbanionic center favor formation of cyclopropanes and suppress competitive β-elimination to the alkylated products. The transformation, demonstrated also on heterocyclic nitroquinoline and nitroindazolines, is an example of transition metal-free dearomatization method.

NOVEL SYNTHESIS OF SELENONES : Application to the Synthesis of Alkyl Cyclopropanecarboxylates.

Krief, A.,Dumont W.,De Mahieu, A.F.

, p. 3269 - 3272 (2007/10/02)

Selenones are prepared by oxidation of selenides by hydrogen peroxide-benzeneseleninic acid.They react with α,β-unsaturated esters and alkylidene malonates in the presence of t-BuOK and produce alkyl cyclopropanecarboxylates.
