116140-95-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116140-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,1,4 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 116140-95:
(8*1)+(7*1)+(6*6)+(5*1)+(4*4)+(3*0)+(2*9)+(1*5)=95
95 % 10 = 5
So 116140-95-5 is a valid CAS Registry Number.

Photooxygenation of chiral dienol ethers: Asymmetric synthesis of alkoxydioxines

Dussault, Patrick H.,Han, Qiang,Sloss, Darby G.,Symonsbergen, David J.

, p. 11437 - 11454 (2007/10/03)

The addition of 1O2 to chiral dienol ethers provides a new route to alkoxydioxines (alkoxyendoperoxides). Depending upon substitution and geometry, the [4+2] cycloaddition is accompanied or even supplanted by [2+2] cycloaddition leading to alkene cleavage and/or ene-like reaction leading to allylic hydroperoxides. The diastereoselectivity of cycloaddition is ultimately limited by the conformational freedom of the dienol ether substrates.
