Check Digit Verification of cas no
The CAS Registry Mumber 911397-27-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,1,3,9 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 911397-27:
(8*9)+(7*1)+(6*1)+(5*3)+(4*9)+(3*7)+(2*2)+(1*7)=168
168 % 10 = 8
So 911397-27-8 is a valid CAS Registry Number.

A dibenzofuran-based host material for blue electrophosphorescence

(Chemical Equation Presented) Dibenzofuran (DBF) is converted to a vacuum-sublimable, electron-transporting host material via 2,8-substitution with diphenylphosphine oxide moieties. Close π-π stacking and the inductive influence of P=O moieties impart favorable electron-transport properties without lowering the triplet energy. A maximum external quantum efficiency of 10.1% and luminance power efficiency of 25.9 lm/W are realized using this material as the host for the blue-green electrophosphorescent molecule, iridium(III) bis(4,6-(di-fluorophenyl)pyridinato-N,C2′)picolinate (Flrpic).
