Check Digit Verification of cas no

The CAS Registry Mumber 727706-53-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,7,7,0 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 727706-53:
(8*7)+(7*2)+(6*7)+(5*7)+(4*0)+(3*6)+(2*5)+(1*3)=178
178 % 10 = 8
So 727706-53-8 is a valid CAS Registry Number.

An expedient synthesis of novel 2-substituted thiazolo[4,5-f]isoquinolines/ quinolines and benzo[1,2-d:4,3-d']bisthiazoles and their potential as inhibitors of COX-1 and COX-2

experimental part, p. 265 - 290 (2011/02/24)

An efficient, general synthesis of 2-substituted thiazolo[4,5-f] isoquinolines, thiazolo[4,5-f]-quinolines and benzo[1,2-d:4,3-d']bisthiazoles has been accomplished from 5-nitroisoquinoline/quinoline and 6-nitrobenzothiazole, respectively, and all the products have been thoroughly identified spectroscopically (IR, 1H and 13C NMR, LR/HR EI/FAB/ESI-MS). The synthesis of thiazolo[4,5-f]isoquinolines constitutes the first synthesis of this class of heteroarenes. Eighteen compounds, covering all three types, were screened for inhibition of COX-1 and COX-2, and some of them showed moderate activities. ARKAT-USA, Inc.
