Check Digit Verification of cas no

The CAS Registry Mumber 403599-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,5,9 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 403599-67:
(8*4)+(7*0)+(6*3)+(5*5)+(4*9)+(3*9)+(2*6)+(1*7)=157
157 % 10 = 7
So 403599-67-7 is a valid CAS Registry Number.

Organic compound based on triazine and benzimidazolone structures and application of organic compound in organic electroluminescent device

-

, (2020/04/17)

The invention relates to an organic compound based on triazine and benzimidazolone structures and an application of the organic compound in an organic electroluminescent device. The structure of the compound simultaneously contains the triazine and benzimidazolone structures, and the compound has high glass transition temperature and molecular thermal stability; the compound is low in absorption and high in refractive index in the field of visible light, and after the compound is applied to a covering layer of an OLED device, the light extraction efficiency of the OLED device can be effectively improved; the compound disclosed by the invention also has a relatively deep HOMO energy level and high electron mobility, can be used as a hole blocking or electron transport layer material of theOLED device, and can effectively block holes or energy from being transmitted from a light emitting layer to one side of an electron layer, thereby improving the recombination efficiency of the holesand electrons in the light emitting layer, improving the light emitting efficiency of the OLED device, and prolonging the service life of the OLED device.
