Check Digit Verification of cas no

The CAS Registry Mumber 1334500-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,5,0 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1334500-68:
(9*1)+(8*3)+(7*3)+(6*4)+(5*5)+(4*0)+(3*0)+(2*6)+(1*8)=123
123 % 10 = 3
So 1334500-68-3 is a valid CAS Registry Number.

Copper-catalyzed C-N bond formation using dialkyl azodicarboxylate as the amination reagent

Samzadeh-Kermani, Alireza

, p. 463 - 465 (2016/01/12)

An efficient copper-catalyzed reaction for C-N bond formation using aryl halides, dialkyl azodicarboxylate, and a hydride source is reported. Using this procedure, aryl iodides reacted at ambient conditions, while aryl bromides required heating to 60 °C to accomplish the transformation. Various functional groups were tolerated under the optimum conditions.

Sodium hydride induced N-arylation of diisopropyl azodicarboxylate by aryl trifluoromethanesulfonates

Yavari, Issa,Ghazanfarpour-Darjani, Majid,Bayat, Mohammad J.,Malekafzali, Alaleh

, p. 942 - 944 (2015/04/27)

A method for intermolecular N-arylation of the anionic species derived from diisopropyl azodicarboxylate and sodium hydride by aryl trifluoromethanesulfonates, in the presence of a ligand-free copper(I) oxide catalyst at 80 °C in N,N-dimethylformamide, is reported. A variety of functionalized aryl triflouromethanesulfonates were efficiently coupled by this method.
