618439-07-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 618439-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,8,4,3 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 618439-07:
(8*6)+(7*1)+(6*8)+(5*4)+(4*3)+(3*9)+(2*0)+(1*7)=169
169 % 10 = 9
So 618439-07-9 is a valid CAS Registry Number.

Low loss electro-optic polymers and devices made therefrom

-

Page/Page column 4-5, (2010/01/31)

The synthesis of novel, high μβ electro-optical chromophores is described. These chromophores are polymerizable with a host polymer or copolymer. The chromophore polymerizable groups comprise epoxy, thioepoxy, oxetane and thiooxetane material which undergo a ring opening polymerization reaction in the presence of a cationic photoinitiator and actinic radiation. The high μβ chromophores, mixed with a selected host polymer, copolymer, oligomer, or one or a plurality of polymerizable monomers, can be used to prepare optical waveguides and other optical elements and/or devices. The electro-optical chromophores of the invention can be used as a replacement for LiNbO3 in the formation of electro-optical devices, particularly electro-optical modulators.
