Check Digit Verification of cas no

The CAS Registry Mumber 28075-35-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,7 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28075-35:
(7*2)+(6*8)+(5*0)+(4*7)+(3*5)+(2*3)+(1*5)=116
116 % 10 = 6
So 28075-35-6 is a valid CAS Registry Number.

Generation of cycloalkynes through deprotonation of cyclic enol triflates with magnesium bisamides

Hioki, Yuto,Okano, Kentaro,Mori, Atsunori

supporting information, p. 2614 - 2617 (2017/03/09)

Deprotonative generation of cyclohexynes, cycloheptynes, and cyclooctynes was achieved by controlling the reactivities of transient anionic species from the corresponding enol triflates with magnesium bis(2,2,6,6-tetramethylpiperidide) as a base. The star

Selective iron-catalyzed cross-coupling reactions of Grignard reagents with enol triflates, acid chlorides, and dichloroarenes

Scheiper, Bodo,Bonnekessel, Melanie,Krause, Helga,Fuerstner, Alois

, p. 3943 - 3949 (2007/10/03)

Cheap, readily available, air stable, nontoxic, and environmentally benign iron salts such as Fe(acac)3 are excellent precatalysts for the cross-coupling of Grignard reagents with alkenyl triflates and acid chlorides. Moreover, it is shown that dichloroarene and -heteroarene derivatives as the substrates can be selectively monoalkylated by this method. All cross-coupling reactions proceed very rapidly under notably mild conditions and turned out to be compatible with a variety of functional groups in both reaction partners. A detailed analysis of the preparative results suggests that iron-catalyzed C-C bond formations can occur via different pathways. Thus, it is likely that reactions of methylmagnesium halides involve iron-ate complexes as the active components, whereas reactions of Grignard reagents with two or more carbon atoms are effected by highly reduced iron-clusters of the formal composition [Fe(MgX)2]n generated in situ. Control experiments using the ate-complex [Me4Fe]Li2 corroborate this interpretation.

The Conversion of Vinyl Triflates into γ'-Hydroxy-α,β-enones

Arcadi, Antonio,Cacchi, Sandro,Marinelli, Fabio

, p. 4955 - 4964 (2007/10/02)

Vinyl triflates have been converted into γ'-hydroxy-α,β-enones through their palladium-catalysed coupling with 1-butyn-4-ols followed by the reaction of the obtained 1-hydroxy-3-yn-5-enes in an acidic CH2Cl2/3N HCl two-phase system in the presence of n-Bu
