75456-44-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75456-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,5 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75456-44:
(7*7)+(6*5)+(5*4)+(4*5)+(3*6)+(2*4)+(1*4)=149
149 % 10 = 9
So 75456-44-9 is a valid CAS Registry Number.

Diastereoselective oxyselenylation of 1,n-diolefins utilizing PET generated [PhSeSePh]+ · as an electrophilic species: An efficient and general strategy for the synthesis of α,α'-trans-dialkyl cyclic ethers

Pandey, Ganesh,Sochanchingwung,Tiwari, Shashi Kant

, p. 1257 - 1258 (2007/10/03)

PET generated electrophilic species [PhSeSePh]+ · is found to effect stereoselective oxyselenylation of 1,n-diolefins (1) leading to a novel strategy for the synthesis of α,α'-trans-dialkyl cyclic ethers (5) in good yields.

PHENYLSELENENYL CHLORIDE AS A REAGENT FOR THE FACILE PREPARATION OF CYCLIC ETHERS FROM DIOLEFINS

Uemura, Sakae,Toshimitsu, Akio,Aoai, Toshiaki,Okano, Masaya

, p. 1533 - 1536 (2007/10/02)

Various cyclic ethers are prepared in good to excellent yields by treating diolefins with phenylselenenyl chloride in aqueous acetonitrile.This is the most facile method for organoselenium-induced formation of cyclic ethers from diolefins so far reported.
