Check Digit Verification of cas no

The CAS Registry Mumber 92345-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,3,4 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 92345-90:
(7*9)+(6*2)+(5*3)+(4*4)+(3*5)+(2*9)+(1*0)=139
139 % 10 = 9
So 92345-90-9 is a valid CAS Registry Number.

TBuO 2H/Cu(acac) 2-Mediated Intramolecular Oxidative Lactonization of o -Allyl Arylaldehydes: Synthesis of 1-Oxoisochromans

Chang, Meng-Yang,Lai, Kai-Xiang,Chen, Kuan-Ting

, p. 527 - 537 (2020/10/19)

A concise route for the tBuO 2H/Cu(acac) 2-mediated synthesis of 1-oxoisochromans is described. This includes: (i) oxidation of oxygenated o -allyl arylaldehydes and (ii) sequential intramolecular lactonization of the resulting olefin-containing benzoic acids. A plausible mechanism is proposed and discussed.

Synthesis of Polysubstituted 3-Methylisoquinolines through the 6π-Electron Cyclization/Elimination of 1-Azatrienes derived from 1,1-Dimethylhydrazine

Vargas, Didier F.,Larghi, Enrique L.,Kaufman, Teodoro S.

supporting information, p. 5605 - 5614 (2018/10/09)

A convenient one pot microwave-assisted 6π-electron cyclization/aromatization approach toward 3-methylisoquinolines is reported. The starting 1-azatriene derivatives were prepared in situ by reaction of 2-propenylbenzaldehydes with 1,1-dimethylhydrazine, which exhibited superior performance when compared with other hydrazine derivatives. Minor amounts of the related 3,4-dihydro isoquinolines were formed concomitantly with the isoquinolines, and a mechanism for their generation was proposed. The reaction conditions were optimized, and its scope and limitations were explored. In general, the transformation proceeded in moderate to good yields.

Synthesis of 2-hydroxymethyl-2,3-dihydrobenzofurans

Chang, Meng-Yang,Lin, Shin-Ying,Chanp, Chieh-Kai

, p. 1905 - 1912 (2014/08/18)

A one-pot protocol toward 2-hydroxymethyl-2,3-dihydrobenzofurans (1) starting with oxygenated o-allylbenzaldehydes (3) was described. The facile one-pot process was carried out by the oxidation of o-allylbenzaldehydes (3) with Oxone in the co-solvent of acetone and DMF in the presence of aqueous EDTA solution and then intramolecular ring-closure of the resulting o-allylphenols (2) in acceptable yields.
