Calculate Digit Verification of CAS Registry Number 1644428-63:
(9*1)+(8*6)+(7*4)+(6*4)+(5*4)+(4*2)+(3*8)+(2*6)+(1*3)=176
176 % 10 = 6
So 1644428-63-6 is a valid CAS Registry Number.

Mn(iii)-mediated cascade cyclization of 1-(azidomethyl)-2-isocyanoarenes with organoboronic acids: Construction of quinazoline derivatives

Kumar, Gujjenahalli Ramalingaiah Yogesh,Begum, Noor Shahina

supporting information, p. 9811 - 9817 (2021/06/15)

A novel and efficient Mn(iii)-mediated oxidative radical cascade reaction of 1-(azidomethyl)-2-isocyanoarenes with organoboronic acids is reported. The single electron oxidation of a commercially available organo boronic acid in the presence of a mild oxidant, Mn(OAc)3·2H2O, resulted in moderate yields of the corresponding quinazoline derivatives.
