Check Digit Verification of cas no

The CAS Registry Mumber 1245284-75-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,2,8 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1245284-75:
(9*1)+(8*2)+(7*4)+(6*5)+(5*2)+(4*8)+(3*4)+(2*7)+(1*5)=156
156 % 10 = 6
So 1245284-75-6 is a valid CAS Registry Number.

Synthesis and photophysical properties of tetrafluorophenyl-modified carbazole oligomers

Hu, Binbin,Wang, Yifei,Chen, Xiaopeng,Zhao, Zujin,Jiang, Zhitao,Lu, Ping,Wang, Yanguang

scheme or table, p. 7583 - 7589 (2010/12/25)

A series of tetrafluorophenyl-modified oligo(3,6-carbazole ethynylene)s (CfCzCf, CfCz2Cf, CfCz3Cf, (CfCz)2Cf, and Cf2CzCf2) were synthesized by a Pd/Cu-catalyzed Sonogashira coupling reaction and fully characterized. Their photophysical and electronic properties as well as their thermal stabilities were investigated. It is noteworthy that these tetrafluorophenyl modified compounds showed relative thermal stabilities and low-lying HOMO levels ranging from -5.54 to -5.60 eV, which might be the promising candidates for hole-transporting materials in OLEDs.
