Check Digit Verification of cas no

The CAS Registry Mumber 1422275-80-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,2,7 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1422275-80:
(9*1)+(8*4)+(7*2)+(6*2)+(5*2)+(4*7)+(3*5)+(2*8)+(1*0)=136
136 % 10 = 6
So 1422275-80-6 is a valid CAS Registry Number.

Isolation, structure, synthesis and cytotoxicity of an unprecedented flupirtine dimer

Csuk, Rene,Sommerwerk, Sven,Wiese, Jana,Wagner, Christoph,Siewert, Bianka,Kluge, Ralph,Stroehl, Dieter

, p. 1297 - 1304 (2013/02/23)

A previously unknown dimer of the well-established analgesic flupirtine has been found, and its structure was revealed by ESI-MS, NMR spectroscopy and an independent synthesis. Thus, starting from 2-amino-6-chloro-3-nitro-pyridine the target compound was obtained in a four-step synthesis. Key-step of this synthesis is a nickel-mediated aryl-aryl coupling. The dimer 4 did not show any cytotoxicity, and its IC50 values were > 30 μm for all six human cancer cell lines and mouse fibroblasts used in this study.
