Check Digit Verification of cas no

The CAS Registry Mumber 1397746-43-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,7,7,4 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1397746-43:
(9*1)+(8*3)+(7*9)+(6*7)+(5*7)+(4*4)+(3*6)+(2*4)+(1*3)=218
218 % 10 = 8
So 1397746-43-8 is a valid CAS Registry Number.

Direct transition metal-free C-S bond formation: Synthesis of 2-aminobenzothiazole derivatives via base-mediated approach

Wang, Rui,Chen, Zhi,Yue, Liang,Pan, Wei,Zhao, Jun-Jie

, p. 4529 - 4531 (2012)

A general, efficient, and more practical protocol for the base-mediated intermolecular or intramolecular S-arylation leading to the 2-aminobenzothiazole derivatives is reported. Remarkably, all reactions were carried out under transition-metal-free conditions with good to excellent yields, rendering the methodology presented herein highly valuable from both environmental and economic points of view.
