Check Digit Verification of cas no

The CAS Registry Mumber 1393673-23-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,6,7 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1393673-23:
(9*1)+(8*3)+(7*9)+(6*3)+(5*6)+(4*7)+(3*3)+(2*2)+(1*3)=188
188 % 10 = 8
So 1393673-23-8 is a valid CAS Registry Number.

Cu(i)-Catalyzed oxidative homo-coupling of thiazoline-4-carboxylates: Synthesis of 4,4′-bithiazoline derivatives

Fang, Xinxin,Zhang, Kaifan,Yao, Hequan,Huang, Yue

, p. 8030 - 8034 (2016/09/09)

Cu(i)-Catalyzed oxidative homo-coupling of thiazoline-4-carboxylates with good functional group tolerance has been developed. The methodology presented an efficient method to directly construct vicinal carbon-hetero quaternary centers existing in numerous functional molecules and could be applied to the synthesis of 4,4′-bithiazoles which are difficult to prepare by direct C-H activation.
