Check Digit Verification of cas no

The CAS Registry Mumber 236389-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,6,3,8 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 236389-21:
(8*2)+(7*3)+(6*6)+(5*3)+(4*8)+(3*9)+(2*2)+(1*1)=152
152 % 10 = 2
So 236389-21-2 is a valid CAS Registry Number.

NOVEL ORGANIC COMPOUND AND MATERIALS FOR ORGANIC ELECTROLUMINESCENT DEVICES COMPRISING THE SAME AND ORGANIC ELECTROLUMINESCENT DEVICES COMPRISING THE SAME

-

Paragraph 0276; 0287-0290, (2020/12/16)

The present invention provides a novel organic compound represented by chemical formula 1, a material for an organic electroluminescent device including the organic compound, and an organic electroluminescent device. The present invention can improve color purity and device life.

Organic electroluminescence device

-

Paragraph 0227-0229, (2019/01/14)

The invention provides an organic electroluminescence device, which relates to the technical field of organic electroluminescence. The organic electroluminescence device is obtained by designing a hole transport layer and/or a luminescent auxiliary layer and an electron transport layer consisting of specific compositions. By virtue of the combination, the electron transport rate can be improved, the hole and electron injection rate can be effectively balanced, the injection balance of a current carrier on a luminescent layer can be realized, the shortening of service life of the device causedby the heat accumulation on interfaces among the electron transport layer, the electron transport layer and the luminescent layer can be avoided, the organic electroluminescence device has the advantages of high luminescent efficiency and long service life, and the problems that the organic electroluminescence device is high in starting voltage, short in service life and low in luminescent efficiency caused by imbalance of the current carrier injection can be effectively solved.

Triazine compound containing fluorene structure and organic luminous device thereof

-

Paragraph 0109; 0110; 0111, (2018/10/11)

The invention discloses a triazine compound containing a fluorene structure and an organic luminous device thereof and relates to the technical field of organic optoelectronic materials. On the one hand, triazine group structures are stable and have high glass transition temperature, high electronic mobility and a low energy level, fluorene groups are three-dimensional spatial structures and can effectively prevent molecular aggregation and inhibit crystallization of molecules, and by means of the advantages of the fluorene groups that the fluorene groups are easy to modify and high in rigidness, the structure of the compound is stable. On the other hand, the triazine groups are combined with the fluorene groups and connected with the fluorene groups through benzene rings or biphenyl rings, conjugated systems are increased, continuous pi-conjugated systems bring great electronic mobility, and therefore high electronic mobility is achieved. Moreover, through the combination of the two kinds of groups, transmission of carriers is balanced. By applying the compound in the organic luminous device to serve as an electronic transmission layer or a cavity blocking layer for use, the device has the advantages that the driving voltage is low and the luminous efficiency is high, and is superior to existing frequently-used OLED devices.
