Check Digit Verification of cas no

The CAS Registry Mumber 2839-52-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,3 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2839-52:
(6*2)+(5*8)+(4*3)+(3*9)+(2*5)+(1*2)=103
103 % 10 = 3
So 2839-52-3 is a valid CAS Registry Number.

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

-

Paragraph 0408-0411, (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
