7304-91-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7304-91-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,0 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7304-91:
(6*7)+(5*3)+(4*0)+(3*4)+(2*9)+(1*1)=88
88 % 10 = 8
So 7304-91-8 is a valid CAS Registry Number.

Green Synthesis of Diaryl Selenides from Arylboronic Acids and Arylseleninic Acids

Redon, Sébastien,Remusat, Vincent,Vanelle, Patrice

supporting information, p. 483 - 487 (2022/02/21)

A new method of deborylative selanylation using arylboronic acids and arylseleninic acids gave diaryl selenoethers and diarylselenoxide. The present approach requires only equimolar arylseleninic acid and led selectively to selenoethers or selenoxides depending on the solvent. The method is metal-free, base- or oxidant-free, efficient, and environmentally friendly.

Synthesis of 9-oxoselenoxanthenium and triarylselenonium hexafluorophosphates

Loskutov,Balina,Russkikh,Shelkovnikov

, p. 1093 - 1097 (2015/06/30)

The selenoxides forming 9-oxoselenoxanthenium and triaryl selenonium hexafluorophosphates via interaction with heptyl phenyl ether and anisole in the MeSO3H-P2O5 mixture followed by treatment with KPF6 have been obtained via selenoxantene-9-one and diphenyl selenide derivatives oxidation with m-chloroperoxybenzoic acid or hydrogen peroxide.
