Check Digit Verification of cas no

The CAS Registry Mumber 439211-43-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,2,1 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 439211-43:
(8*4)+(7*3)+(6*9)+(5*2)+(4*1)+(3*1)+(2*4)+(1*3)=135
135 % 10 = 5
So 439211-43-5 is a valid CAS Registry Number.

Cunning metal core: Efficiency/stability dilemma in metallated porphyrin based light-emitting electrochemical cells

Weber, Katharina T.,Karikis, Kostas,Weber, Michael D.,Coto, Pedro B.,Charisiadis, Asterios,Charitaki, Despina,Charalambidis, Georgios,Angaridis, Panagiotis,Coutsolelos, Athanassios G.,Costa, Rubén D.

supporting information, p. 13284 - 13288 (2016/09/04)

The syntheses, photophysical/electrochemical characterizations of different metallated porphyrins-i.e., Zn2+, Pt2+, Pd2+, and Sn4+ porphyrins-as well as their first application in light-emitting electrochemical cells are provided. A direct comparison demonstrates that depending on the metallation either efficient (Pt-por) or stable (Zn-por) devices are achieved, demonstrating that the choice of the metal core is a key aspect for future developments.
