Check Digit Verification of cas no

The CAS Registry Mumber 40932-71-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,3 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40932-71:
(7*4)+(6*0)+(5*9)+(4*3)+(3*2)+(2*7)+(1*1)=106
106 % 10 = 6
So 40932-71-6 is a valid CAS Registry Number.

Ligand-Enabled Gold-Catalyzed C(sp2)-N Cross-Coupling Reactions of Aryl Iodides with Amines

Akram, Manjur O.,Das, Avishek,Chakrabarty, Indradweep,Patil, Nitin T.

supporting information, p. 8101 - 8105 (2019/10/11)

The first example of ancillary (P,N)-ligand-enabled gold-catalyzed C-N cross-coupling reactions of aryl iodides with amines is reported. The high generality of the reaction in de novo synthesis, late-stage modifications, and cascade processes to access functionalized indolinones and carbazoles underscores the synthetic potential of the presented strategy. Monitoring the reaction with ESI-HRMS and NMR provided strong evidence for the in situ formation of putative high valent Au(III) intermediates.
