Check Digit Verification of cas no

The CAS Registry Mumber 1127561-38-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,7,5,6 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1127561-38:
(9*1)+(8*1)+(7*2)+(6*7)+(5*5)+(4*6)+(3*1)+(2*3)+(1*8)=139
139 % 10 = 9
So 1127561-38-9 is a valid CAS Registry Number.

Copper-catalyzed direct amination of 1,2,3-triazole N-oxides by C-H activation and C-N coupling

Zhu, Jiayi,Kong, Yubo,Lin, Feng,Wang, Baoshuang,Chen, Zhengwang,Liu, Liangxian

, p. 1507 - 1515 (2015)

An efficient approach for the synthesis of 4-amino-2-aryl- 1,2,3-triazole derivatives has been developed through the copper-catalyzed direct C-H amination of 2-aryl-1,2,3-triazole N-oxides under mild reaction conditions. Various amines, including primary and secondary aliphatic and aromatic amines, can be employed as effective coupling partners. The general performance of our method was also demonstrated by the oxidative amination of thiazole and imidazole N-oxides.
