Check Digit Verification of cas no

The CAS Registry Mumber 203396-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,3,9 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 203396-98:
(8*2)+(7*0)+(6*3)+(5*3)+(4*9)+(3*6)+(2*9)+(1*8)=129
129 % 10 = 9
So 203396-98-9 is a valid CAS Registry Number.

Photophysical and biological investigation of novel luminescent Ru(ii)-polypyridyl-1,8-naphthalimide Troeger's bases as cellular imaging agents

Elmes, Robert B. P.,Erby, Marialuisa,Bright, Sandra A.,Williams, D. Clive,Gunnlaugsson, Thorfinnur

, p. 2588 - 2590 (2012)

The synthesis and photophysical properties of 1 and 2, two Ru(ii)-polypyridyl based-1,8-naphthalimide Troeger's bases, are described; these were found to stabilize double stranded DNA, undergo rapid cellular uptake, displaying good luminescence without affecting cell viability even after 24 hours of incubation. This journal is The Royal Society of Chemistry 2012.
