Check Digit Verification of cas no

The CAS Registry Mumber 5440-76-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,4 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5440-76:
(6*5)+(5*4)+(4*4)+(3*0)+(2*7)+(1*6)=86
86 % 10 = 6
So 5440-76-6 is a valid CAS Registry Number.

Tris(4-methoxyphenyl)methanol

Ferguson, George,Glidewell, Christopher,Patterson, Iain L. J.

, p. 420 - 423 (1996)

Tris(4-methoxyphenyl)methanol, C22H22O4, crystallizes in space group P21 with two molecules in the asymmetric unit. The molecules are linked into dimers by a weak O-H...O hydrogen bond [O...O 3.035 (3) A].

Electrochemical and Spectroscopic Studies on Triarylamine-Polychlorotriphenylmethyl Dyads with Particularly Strong Triarylamine Donors

Breimaier, Stefanie,Winter, Rainer F.

, p. 4690 - 4700 (2021/09/10)

We present two new donor-acceptor dyads composed of a polychlorotriphenylmethyl radical (PTM.) as the acceptor (A) and bis(4-dimethylaminophenyl)(phenyl)amine (TPAN) or 2,2’:6’,2’’:6’’,6-trioxytriphenylamine (TOTA) as particularly electron-rich triarylamine (TAA) donors (D). We assessed their electrochemical properties and electronic structures by cyclic voltammetry, UV/vis/NIR spectroscopy, EPR spectroscopy and quantum chemical calculations. By establishing the spectroscopic fingerprints of the oxidized and reduced forms, we probe for the possible coexistence of a zwitterionic TAA+-PTM? valence tautomer (VT), besides neutral TAA-PTM.. UV/vis/NIR and EPR spectroscopic studies at variable temperature and in various solvents however provide no indication for such equilibria. Quantitative spin counting experiments by EPR spectroscopy and quantum chemical calculations indicate that the one-electron oxidized forms of these dyads possess an open-shell singlet ground state which is energetically slightly below the triplet state.

Exploration of mechanochemical activation in solid-state fluoro‐grignard reactions

Hanusa, Timothy P.,Speight, Isaiah R.

supporting information, (2020/02/06)

Owing to the strength of the C–F bond, the ‘direct’ preparation of Grignard reagents, i.e., the interaction of elemental magnesium with an organic halide, typically in an ethereal solvent, fails for bulk magnesium and organofluorine compounds. Previously described mechanochemical methods for preparing Grignard reagents have involved ball milling powdered magnesium with organochlorines or bromines. Activation of the C–F bond through a similar route is also possible, however. For example, milling 1- and 2-fluoronaphthalene with an excess of magnesium metal for 2 h, followed by treatment with FeCl3 and additional milling, produces the corresponding binaphthalenes, albeit in low yields (ca. 20%). The yields are independent of the particular isomer involved and are also comparable to the yields from corresponding the bromonaphthalenes. These results may reflect similar charges that reside on the α-carbon in the naphthalenes, as indicated by density functional theory calculations.

An Efficient Ga(OTf)3/Isopropanol Catalytic System for Direct Reduction of Benzylic Alcohols

Sai, Masahiro

supporting information, p. 4330 - 4335 (2018/10/15)

This study aims to report the first gallium-catalyzed direct reduction of benzylic alcohols using isopropanol as a reductant. The reaction proceeds via gallium catalyst-assisted hydride transfer of the in situ-generated benzylic isopropyl ether. The method generates only water and acetone as byproducts and thus provides an atom-economic and environmentally friendly approach to the synthesis of di- and triarylmethanes, which are important substructures in various bioactive compounds and functional materials. (Figure presented.).
