Check Digit Verification of cas no

The CAS Registry Mumber 69571-02-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,7 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 69571-02:
(7*6)+(6*9)+(5*5)+(4*7)+(3*1)+(2*0)+(1*2)=154
154 % 10 = 4
So 69571-02-4 is a valid CAS Registry Number.

A series of CBP-derivatives as host materials for blue phosphorescent organic light-emitting diodes

Schroegel, Pamela,Tomkeviciene, Ausra,Strohriegl, Peter,Hoffmann, Sebastian T.,Koehler, Anna,Lennartz, Christian

experimental part, p. 2266 - 2273 (2011/10/12)

We report a series of CBP-derivatives with superior thermal and electronic properties for the use as host materials for blue electrophosphorescent organic light emitting diodes. We applied a systematic variation of the substitution pattern in the 2- and 2′-position of the biphenyl unit and the 3- and 6-position of the carbazole moieties. In contrast to the crystalline parent compound CBP, all methyl and trifluoromethyl substituted derivatives show amorphous behaviour. Substitution in the 2- and 2′-position of the biphenyl causes a twisting of the phenyl rings. Hence, the degree of conjugation of the molecules is limited which leads to enlarged triplet energies of approximately 2.95 eV compared to 2.58 eV for CBP. The methyl substitution at the active 3- and 6-position of the pendant carbazole units yields materials with an electrochemically stable behaviour against oxidation. The Royal Society of Chemistry.
