16522-41-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16522-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,2 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16522-41:
(7*1)+(6*6)+(5*5)+(4*2)+(3*2)+(2*4)+(1*1)=91
91 % 10 = 1
So 16522-41-1 is a valid CAS Registry Number.

Control of the Alternating Sequence for N-Isopropylacrylamide (NIPAM) and Methacrylic Acid Units in a Copolymer by Cyclopolymerization and Transformation of the Cyclopendant Group

Kametani, Yuki,Sawamoto, Mitsuo,Ouchi, Makoto

, p. 10905 - 10909 (2018)

An alternating copolymer of methacrylic acid and N-isopropyl acrylamide (NIPAM) was synthesized by selective cyclopolymerization of a special divinyl monomer and transformation of repeating cyclo-units in the resultant cyclopolymer. Crucial to the breakthrough is the monomer design in view of two types of cleavable bonds (3° ester and activated ester) in the pendant group of the monomer and the lower reactivity ratio of the two double bonds (methacrylate and electron-poor acrylate) for the polymerizable groups. The thus-obtained cyclopolymer was transformed into the alternating copolymer by transformation of the activated ester into amide by isopropyl amine and cleavage of the 3° ester by trifluoroacetic acid. The resultant copolymer showed thermal and pH response in aqueous solution that was different from the 1:1 random copolymer as well as the homopolymers.

Isothiourea-catalysed transfer hydrogenation of α,β-unsaturated para-nitrophenyl esters

Smith, Andrew D.,Wu, Jiufeng,Young, Claire M.

supporting information, (2020/12/21)

A protocol for the isothiourea-catalysed transfer hydrogenation of α,β-unsaturated para-nitrophenyl esters using Hantzsch ester has been developed. Good to excellent yields are observed using α,β-unsaturated aryl esters bearing electron-withdrawing β-subs

Synthesis, characterization and reactivity ratios of co-polymers derived from 4-nitrophenyl methacrylate and butyl methacrylate

Thamizharasi,Gnanasundaram

, p. 288 - 292 (2007/10/03)

Poly (NPNA) has been synthesized from 4-nitrophenylmethacrylate (NPMA) in 2-butanone using BPO as a free radical initiator. Copolymers of NPMA and BMA [poly(NPMA-co-BMA)] have also likewise been obtained. The polymers have been characterized by IR, 1
