Check Digit Verification of cas no
The CAS Registry Mumber 3263-46-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,6 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3263-46:
(6*3)+(5*2)+(4*6)+(3*3)+(2*4)+(1*6)=75
75 % 10 = 5
So 3263-46-5 is a valid CAS Registry Number.

Page/Page column 4, (2010/02/11)
This invention pertains to certain novel colorant compounds containing one or more ethylenically-unsaturated, photopolymerizable radicals that may be copolymerized (or cured) with ethylenically-unsaturated monomers to produce colored compositions such as colored acrylic polymers. Suitable compositions having the present colorants copolymerized therein include, e.g., polymers produced from acrylate and methacrylate esters, colored polystyrenes, and similar colored polymeric materials derived from other ethylenically-unsaturated monomers. The present invention also pertains to processes for preparing the photopolymerizable colorant compounds. The ethylenically unsaturated colorant compounds may be suitable for use in coatings that are applied to wood, glass, metal, thermoplastics and the like.
