52249-38-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52249-38-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,4 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52249-38:
(7*5)+(6*2)+(5*2)+(4*4)+(3*9)+(2*3)+(1*8)=114
114 % 10 = 4
So 52249-38-4 is a valid CAS Registry Number.

Eaton's reagent assisted aromatic C-C coupling of carbazoles for optoelectronic applications

Yuan, Jie,Jin, Lu,Chen, Runfeng,Tang, Xingxing,Xie, Xiang,Tang, Yuting,Huang, Wei

, p. 14704 - 14708 (2018)

An Eaton's reagent assisted C(sp2)-C(sp2) coupling via the Scholl reaction mechanism was developed to prepare bicarbazoles without using any solvents and catalysts. The resulting biaryl exhibits unique optoelectronic properties as a promising host material of blue phosphorescent organic light emitting diodes, achieving high current efficiency up to 31.7 cd A-1 with ultralow roll-off.
