Check Digit Verification of cas no

The CAS Registry Mumber 1421789-45-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,7,8 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1421789-45:
(9*1)+(8*4)+(7*2)+(6*1)+(5*7)+(4*8)+(3*9)+(2*4)+(1*5)=168
168 % 10 = 8
So 1421789-45-8 is a valid CAS Registry Number.

Robust phosphorescent platinum(ii) complexes with tetradentate O ∧N∧C∧N ligands: High efficiency OLEDs with excellent efficiency stability

Kui, Steven C. F.,Chow, Pui Keong,Cheng, Gang,Kwok, Chi-Chung,Kwong, Chun Lam,Low, Kam-Hung,Che, Chi-Ming

supporting information, p. 1497 - 1499 (2013/03/14)

The Pt(ii) complexes (1-3) bearing tetradentate O∧N ∧C∧N ligands display high emission quantum yields (0.76-0.90) and good thermal stability (Td > 400 °C). Complex 3 is an excellent green phosphorescence dopant for OLEDs with excellent efficiency and low efficiency roll-off (ηL, η Ext(max) = 66.7 cd A-1, 18.2%; ηL, ηExt (1000 cd m-2) = 65.1 cd A-1, 17.7%).
