Check Digit Verification of cas no

The CAS Registry Mumber 33139-83-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,3 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33139-83:
(7*3)+(6*3)+(5*1)+(4*3)+(3*9)+(2*8)+(1*3)=102
102 % 10 = 2
So 33139-83-2 is a valid CAS Registry Number.

Heat-resistant poly(N-(1-phenylethyl)maleimide-co-styrene) microspheres prepared by dispersion polymerization

Tong, Linyue,Cui, Xin,Yang, Wantai,Deng, Jianping

supporting information; experimental part, p. 6697 - 6703 (2012/08/08)

This article reports on a novel type of polymeric microsphere consisting of poly(N-(1-phenylethyl)maleimide-co-styrene) (poly(N-PEMI-co-St)) and showing remarkable heat resistance. Such microspheres were prepared by dispersion polymerization with 2,2′-azo

Base-induced alcoholysis of N-arylmaleimides: Facile in situ oxa-Michael addition to alkyl maleanilates: Two-step one-pot rapid access to alkoxysuccinic acids

Mhaske, Santosh B.,Argade, Narshinha P.

, p. 863 - 870 (2007/10/03)

A simple, efficient and general two-step, one-pot approach to alkoxysuccinic acids is described. The potassium carbonate-catalyzed reactions of alcohols with N-p-tolylmaleimide (4) followed by an acid-induced hydrolysis of intermediate products furnished alkoxysuccinic acids 1a-f in 90-98% yields. All the intermediates from the reaction of imide 4 with alcohols have been isolated and characterized, proving that the in situ formed alkyl maleanilates 3 are the actual Michael acceptors.

Use of readily available monomers in the synthesis of vinyl copolymers with optical activity arising from the configuration of stereogenic carbon atoms in the main chain

Donnelly, Irene H.,Kambouris, Peter,Nonhebel, Derek C.,Rohr, Thomas,Sherrington, David C.

, p. 1821 - 1829 (2007/10/03)

The present work was aimed at synthesising vinyl copolymers with optical activity arising only from the configuration of the stereogenic carbon atoms in the main chain. By copolymerising optically active diesters of fumaric acid with styrene, backbones wi

Diastereoselective Diels-Alder reactions between substituted 1,3-butadienes and N-α-methylbenzylmaleimide

Baldwin,Greenspan,Alaimo,McPhail

, p. 5877 - 5880 (2007/10/02)

The TiCl4 catalyzed reaction between 2-t-butyl-1,3-butadiene and N-α-methylbenzylmaleimide at -65°C affords diastereomeric Diels-Alder adducts in a 15:1 ratio. The structure of the major adduct was determined by x-ray.
