Check Digit Verification of cas no

The CAS Registry Mumber 253141-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,1,4 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 253141-35:
(8*2)+(7*5)+(6*3)+(5*1)+(4*4)+(3*1)+(2*3)+(1*5)=104
104 % 10 = 4
So 253141-35-4 is a valid CAS Registry Number.

Red-shifted trisaryl-1,3,5-triazine ultraviolet light absorbers

-

Page column 54-57, (2008/06/13)

This invention relates generally to red-shifted trisaryl-1,3,5-triazines and the use thereof to protect against degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxidation, moisture, atmospheric pollutants and combinations thereof. The new class of trisaryl-1,3,5-triazines comprises an aryl ring attached to the triazine ring [and preferably an aryl ring containing a hydroxyl group, either free or blocked to form a latent stabilizer, ortho- to the point of attachment to the triazine ring (2-position) and a hydroxyl group or a moiety joined by an ether linkage para- to the point of attachment to the triazine ring (4-position)] substituted at the 3-position or disubstituted at the 3- and 5-positions with a group comprising an amide and/or an amine. These materials may be incorporated into formulations comprising coatings, polymers, resins, organic compounds and the like. A method for stabilizing a material by incorporating such red-shifted trisaryl-1,3,5-triazines is also disclosed.
