393-19-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 393-19-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 393-19:
(5*3)+(4*9)+(3*3)+(2*1)+(1*9)=71
71 % 10 = 1
So 393-19-1 is a valid CAS Registry Number.

DIAMINE COMPOUND, AND POLYIMIDE PRECURSOR AND POLYIMIDE FILM PREPARED BY USING THE SAME

-

, (2020/11/03)

The present invention disclosed a novel diamine compound including a structure in which a phenylene linker (L) connecting an intramolecular imide ring and the imide ring is bonded to a phenyl ring substituted with -NH-(C=O)- or -O-(C=O)-. A polyimide film prepared by polymerizing the novel diamine compound has not only improved mechanical and thermal properties, but also an excellent refractive index.COPYRIGHT KIPO 2021
