17831-64-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17831-64-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,3 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17831-64:
(7*1)+(6*7)+(5*8)+(4*3)+(3*1)+(2*6)+(1*4)=120
120 % 10 = 0
So 17831-64-0 is a valid CAS Registry Number.

Fumaric acid derivates and ophtalmic lenses using the same

-

Page/Page column 10, (2008/12/06)

The present invention relates to fumaric acid derivatives and ophthalmic lenses using them. More specifically, the present invention relates to a fumaric acid derivative having a hydrophilic group and a silicon-containing alkyl group within a molecule, and to contact lenses or intraocular lenses. The fumaric acid derivatives of the present invention provide, on one hand, superior oxygen permeability by having a silicon-containing alkyl group within the molecular structure, and on the other hand, improved compatibility with other hydrophilic monomers by having a hydrophilic group within the same molecule. When ophthalmic lenses obtained by polymerizing monomer compositions containing the fumaric acid derivative are constructed as, for example, water content lenses, lenses with high oxygen permeability independent from the water content may be obtained, wherein the fumaric acid derivatives is superior in compatibility with the hydrophilic monomer used in combination and allows the combination in various mixing ratios.
