General Description
N,N'-Bis[4-(1-naphthalenylphenylamino)phenyl]-N,N'-diphenyl-[1,1'-biphenyl]-4,4'-diamine is a chemical compound also known as α-NPD. It is a commonly used organic semiconductor material for electronic devices, especially in the production of organic light-emitting diodes (OLEDs). α-NPD has excellent hole-transporting properties, making it a crucial component in OLEDs, which are used in display screens, lighting, and other applications. Its chemical structure consists of biphenyl and naphthalene groups, and its properties make it a vital ingredient in the development of advanced electronic technologies. However, like many other organic compounds, α-NPD should be handled and used with proper safety precautions in place.
Check Digit Verification of cas no
The CAS Registry Mumber 209980-47-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,9,8 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 209980-47:
(8*2)+(7*0)+(6*9)+(5*9)+(4*8)+(3*0)+(2*4)+(1*7)=162
162 % 10 = 2
So 209980-47-2 is a valid CAS Registry Number.
