Check Digit Verification of cas no

The CAS Registry Mumber 126798-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,7,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 126798-20:
(8*1)+(7*2)+(6*6)+(5*7)+(4*9)+(3*8)+(2*2)+(1*0)=157
157 % 10 = 7
So 126798-20-7 is a valid CAS Registry Number.

Copper-catalyzed carboxamide-directed ortho amination of anilines with alkylamines at room temperature

Li, Qiong,Zhang, Shu-Yu,He, Gang,Ai, Zhaoyan,Nack, William A.,Chen, Gong

supporting information, p. 1764 - 1767 (2014/04/17)

In this report, a highly efficient method for the room temperature installation of alkyl amino motifs onto the ortho position of anilines via Cu-catalyzed carboxamide-directed amination with alkylamines is described. This method offers a practical solution for the rapid synthesis of complex arylamines from simple starting materials and enables new planning strategies for the construction of arylamine-containing pharmacophores. A single electron transfer (SET)-mediated mechanism is proposed.
