Check Digit Verification of cas no

The CAS Registry Mumber 102884-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,8,8 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 102884-08:
(8*1)+(7*0)+(6*2)+(5*8)+(4*8)+(3*4)+(2*0)+(1*8)=112
112 % 10 = 2
So 102884-08-2 is a valid CAS Registry Number.

Emitters with a pyridine-3,5-dicarbonitrile core and short delayed fluorescence lifetimes of about 1.5 μs: Orange-red TADF-based OLEDs with very slow efficiency roll-offs at high luminance

The efficiency roll-off with increasing brightness in thermally activated delayed fluorescence (TADF)-based OLEDs greatly impedes their future applications. The combination of varying numbers of phenoxazine (PXZ) donors with pyridine-3,5-dicarbonitrile (PCN) acceptors has afforded three orange-red TADF emitters PXZ-PCN, bis-PXZ-PCN and tri-PXZ-PCN. The singlet-triplet energy gap (ΔEST) of the molecules is in good agreement with that predicted by corrected time-dependent density functional theory. When bis-PXZ-PCN is doped into the host material CBP (10 wt%), the ΔEST value of 0.04 eV is achieved, and this facilitates effective reverse intersystem crossing (RISC, kRISC = 9.8 × 105 s-1). Bis-PXZ-PCN endows its device with orange-red electroluminescence peak at 600 nm, accompanied by maximum external quantum efficiency of 9.8% and an impressive slow efficiency roll-off of 15% at a high luminance of 1000 cd m-2, which is among the lowest roll-off value of the reported orange-red to red TADF-based OLEDs.
