69698-20-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69698-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,6,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69698-20:
(7*6)+(6*9)+(5*6)+(4*9)+(3*8)+(2*2)+(1*0)=190
190 % 10 = 0
So 69698-20-0 is a valid CAS Registry Number.

Synthesis of a novel water-soluble polymeric UV-absorber for cotton

Ma, Wei,Jiang, Xue,Liu, Yong,Tang, Bing Tao,Zhang, Shu Fen

, p. 1489 - 1491 (2011)

A water-soluble polymeric UV-absorber with polyvinylamine as backbone and benzotriazole type UV absorber as anti-UV functional group was synthesized by grafting brominated (2′-acetoxy-5′-methylphenyl)-2H-benzotriazole onto polyvinylamine. The intermediate

UV-ABSORBING VINYLIC MONOMERS AND USES THEREOF

-

Paragraph 0211; 0212; 0213, (2017/09/08)

Described herein are water-soluble UV-absorbing vinylic monomers and their uses in preparing UV-absorbing contact lenses capable of blocking ultra-violet (“UV”) radiation and optionally (but preferably) violet radiation with wavelengths from 380 nm to 440

Synthesis of new ultraviolet light absorbers based on 2-aryl-2H- benzotriazoles

Koutsimpelis, Aristides G.,Screttas, Constantinos G.,Igglessi-Markopoulou, Olga

, p. 1393 - 1401 (2007/10/03)

A procedure for the synthesis of some new ultraviolet absorbers of the benzotriazole series is reported. The compounds bear a carboxylic or a formyl group para to the hydroxy group, and these functionalities impart to the absorbers improved compatibility with certain disperse dyes on polyester fibers.
