General Description
TRANS,TRANS-4''-(4''-PROPYLBICYCLOHEXYL-4-YL)-3,4-DIFLUOROBIPHENYL is a chemical compound that belongs to the family of biphenyls. It consists of two benzene rings connected by a carbon-carbon double bond, with two fluorine atoms attached to one of the rings. Additionally, there is a 4-propylbicyclohexyl-4-yl group attached to the biphenyl structure. TRANS,TRANS-4''-(4''-PROPYLBICYCLOHEXYL-4-YL)-3,4-DIFLUOROBIPHENYL is used in the manufacturing of liquid crystal displays (LCDs) and as a component in other electronic applications, due to its ability to align liquid crystals and promote the uniform orientation of molecules. It also exhibits unique thermal, optical, and electrical properties which make it suitable for use in these applications.
Check Digit Verification of cas no
The CAS Registry Mumber 119990-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,9 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119990-81:
(8*1)+(7*1)+(6*9)+(5*9)+(4*9)+(3*0)+(2*8)+(1*1)=167
167 % 10 = 7
So 119990-81-7 is a valid CAS Registry Number.
