Check Digit Verification of cas no

The CAS Registry Mumber 40888-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,8 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40888-26:
(7*4)+(6*0)+(5*8)+(4*8)+(3*8)+(2*2)+(1*6)=134
134 % 10 = 4
So 40888-26-4 is a valid CAS Registry Number.

An unprecedented exploration of tertiary amines as alkyl radical equivalents for cross-coupling with aromatic alkynes to access allylarenes has been achieved by a P/N heteroleptic Cu(I)based photosensitizer under photoredox catalysis conditions. Mechanist

Sulfuryl Fluoride Mediated Conversion of Aldehydes to Nitriles

Gurjar, Jitendra,Bater, Jorick,Fokin, Valery V.

supporting information, p. 1906 - 1909 (2019/01/24)

Aliphatic, aromatic, and heteroaromatic aldehydes were readily converted to corresponding nitriles in a one-pot reaction sequence with hydroxylamine and sulfuryl fluoride. The reaction proceeds at room temperature, does not require metal catalysts and special precautions, and produces nitriles in excellent yields. It is compatible with a variety of functional groups, can be performed in aqueous and organic solvents, and is readily scalable to multigram quantities. Mild conditions and high selectivity of the reaction enabled the construction of polyfunctional probes containing nitrile, alkyne, azide, and fluorosulfate groups for further orthogonal derivatization.

Gold(i)-catalyzed cross-coupling reactions of aryldiazonium salts with organostannanes are described. This redox neutral strategy offers an efficient approach to diverse biaryls, vinyl arenes and arylacetylenes. Monitoring the reaction with NMR and ESI-MS provided strong evidence for the in situ formation of Ph3PAuIR (R = aryl, vinyl and alkynyl) species which is crucial for the activation of aryldiazonium salts.

Formation of indoles, dihydroisoquinolines, and dihydroquinolines by ruthenium-catalyzed heterocyclizations

Varela-Fernández, Alejandro,Varela, Jesús A.,Saá, Carlos

, p. 3285 - 3295 (2013/01/15)

Indoles, dihydroisoquinolines, and dihydroquinolines were efficiently prepared by ruthenium-catalyzed heterocyclizations of aromatic homo- and bis-homopropargyl amines/amides in the presence of an amine/ammonium base-acid pair. These regioselective 5-endo and 6-endo cyclizations most probably occur by nucleophilic trapping of key ruthenium-vinylidene intermediates. Georg Thieme Verlag Stuttgart · New York.

Ruthenium-catalyzed cycloisomerization of aromatic homo- and bis-homopropargylic amines/amides: Formation of indoles, dihydroisoquinolines and dihydroquinolines

Varela-Fernandez, Alejandro,Varela, Jesus A.,Saa, Carlos

, p. 1933 - 1937 (2011/10/08)

Ruthenium-catalyzed cycloisomerizations of aromatic homo- and bis-homopropargylic amines/amides efficiently afford indoles, dihydroisoquinolines and dihydroquinolines. These processes were regioselective (5- and 6-endo cyclizations) on using key Ru vinylidene intermediates. The presence of an amine/ammonium base-acid pair increased the rate of cyclization and facilitated the catalytic turnover. Copyright
