Check Digit Verification of cas no

The CAS Registry Mumber 298219-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,8,2,1 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 298219-06:
(8*2)+(7*9)+(6*8)+(5*2)+(4*1)+(3*9)+(2*0)+(1*6)=174
174 % 10 = 4
So 298219-06-4 is a valid CAS Registry Number.

Copper-Catalyzed Coupling of Oxime Acetates with Isothiocyanates: A Strategy for 2-Aminothiazoles

Tang, Xiaodong,Zhu, Zhongzhi,Qi, Chaorong,Wu, Wanqing,Jiang, Huanfeng

supporting information, p. 180 - 183 (2016/02/03)

A new strategy for 2-aminothiazoles is developed via the copper-catalyzed coupling of oxime acetates with isothiocyanates. Various 4-substituted and 4,5-disubstituted 2-aminothiazoles were formed smoothly under mild reaction conditions. This process involved copper-catalyzed N-O bond cleavage, activation of vinyl sp2 C-H bonds, and C-S/C-N bond formations. It is noteworthy that the oxime acetates were used not only as a substrate but also as a single oxidant.
