Check Digit Verification of cas no

The CAS Registry Mumber 5738-23-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,3 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5738-23:
(6*5)+(5*7)+(4*3)+(3*8)+(2*2)+(1*3)=108
108 % 10 = 8
So 5738-23-8 is a valid CAS Registry Number.

An efficient and unprecedented method to the synthesis of 1-azathioxanthone derivatives has been developed by means of palladium-catalyzed C(formyl)-C(aryl) coupling followed by SNAr reaction. Optimization study was carried out through different catalyst,

Cobalt-Catalyzed Electrophilic Aminations with Anthranils: An Expedient Route to Condensed Quinolines

Li, Jie,Tan, Eric,Keller, Niklas,Chen, Yi-Hung,Zehetmaier, Peter M.,Jakowetz, Andreas C.,Bein, Thomas,Knochel, Paul

supporting information, p. 98 - 103 (2019/01/08)

The reaction of various organozinc pivalates with anthranils provides anilines derivatives, which cyclize under acidic conditions providing condensed quinolines. Using alkenylzinc pivalates, electron-rich arylzinc pivalates or heterocyclic zinc pivalates produces directly the condensed quinolines of which several structures belong to new heterocyclic scaffolds. These N-heterocycles are of particular interest for organic light emitting diodes with their high photoluminescence quantum yields and long exciton lifetimes as well as for hole-transporting materials in methylammonium lead iodide perovskites solar cells due to an optimal band alignment for holes and a large bandgap.
