Check Digit Verification of cas no
The CAS Registry Mumber 20688-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,8 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20688-40:
(7*2)+(6*0)+(5*6)+(4*8)+(3*8)+(2*4)+(1*0)=108
108 % 10 = 8
So 20688-40-8 is a valid CAS Registry Number.

Merging Halogen-Atom Transfer (XAT) and Cobalt Catalysis to Override E2-Selectivity in the Elimination of Alkyl Halides: A Mild Route towardcontra-Thermodynamic Olefins

We report here a mechanistically distinct tactic to carry E2-type eliminations on alkyl halides. This strategy exploits the interplay of α-aminoalkyl radical-mediated halogen-atom transfer (XAT) with desaturative cobalt catalysis. The methodology is high-yielding, tolerates many functionalities, and was used to access industrially relevant materials. In contrast to thermal E2 eliminations where unsymmetrical substrates give regioisomeric mixtures, this approach enables, by fine-tuning of the electronic and steric properties of the cobalt catalyst, to obtain high olefin positional selectivity. This unprecedented mechanistic feature has allowed access tocontra-thermodynamic olefins, elusive by E2 eliminations.
Oxygen-17 Nuclear Magnetic Resonance Spectral Investigation of 3-Alkoxy-trans-3,4-Disubstituted-Thiolane 1,1-Dioxides and Related Compounds

The (17)O NMR spectra of 3-alkoxythiolane 1,1-dioxides indicate that the sulfonyl oxygens are diastereotopic but their chemical shift differences are essentially independent of the structure of the alkyl group in the alkoxy moiety.Eu(fod)3 enhances the (17)O chemical shift difference between the diastereotopic sulfonyl oxygens in 3-isopropoxythiolane 1,1-dioxide and shifts both oxygens upfield. α,β-Unsaturation deshields the sulfonyl oxygens in both five- and six-membered rings.
