Check Digit Verification of cas no

The CAS Registry Mumber 1392827-19-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,2,8,2 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1392827-19:
(9*1)+(8*3)+(7*9)+(6*2)+(5*8)+(4*2)+(3*7)+(2*1)+(1*9)=188
188 % 10 = 8
So 1392827-19-8 is a valid CAS Registry Number.

Ruthenium-Catalyzed Oxidative Amidation of Alkynes to Amides

álvarez-Pérez, Andrea,Esteruelas, Miguel A.,Izquierdo, Susana,Varela, Jesús A.,Saá, Carlos

, p. 5346 - 5350 (2019)

Complex CpRuCl(PPh3)2 catalyzes reactions of terminal alkynes with 4-picoline N-oxide and primary and secondary amines to afford the corresponding amides. The reactions occur in chlorinated solvent and aqueous medium, showing applications in peptide chemistry. Stoichiometric studies reveal that the true catalysts of the processes are the vinylidene cations [CpRu(=C=CHR)(PPh3)2]+ which are oxidized to the Ru(η2-CO)-ketenes by the N-oxide. Finally, nucleophilic additions of primary and secondary amines to the free ketenes yield the corresponding amides.
