Check Digit Verification of cas no
The CAS Registry Mumber 4664-49-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4664-49:
(6*4)+(5*6)+(4*6)+(3*4)+(2*4)+(1*9)=107
107 % 10 = 7
So 4664-49-7 is a valid CAS Registry Number.

Hydroxy functional acrylate and methacrylate monomers prepared via lipase-catalyzed transacylation reactions
Popescu, Dragos,Hoogenboom, Richard,Keul, Helmut,Moeller, Martin
experimental part, p. 80 - 89 (2010/08/20)
Candida antarctica lipase B (CAL-B, Novozyme 435) catalyzes the transacylation of methyl acrylate and methyl methacrylate with diols and triols in 2-methyl-2-butanol at 50 °C. Under the experimental conditions, up to 70 mol% of the acyl donor methyl acrylate was converted. Methyl methacrylate is the less efficient acyl donor (up to 60 mol%) due to the higher sterical hindrance in the enzymatic transacylation. Under the reaction conditions high yields of the mono-acylated products are obtained, which contain minor amounts of bis(meth)acrylates. In addition it was observed that Novozyme 435 catalyzes regioselectively the acylation of the primary hydroxyl groups. In comparison with the chemical catalyzed route no selectivity was observed for unsubstituted diols. For substituted diols more mono-acylated product was formed in the lipase-catalyzed reaction than in the chemical catalyzed reaction.
High solids acrylic coating systems

, (2008/06/13)
High solids acrylic coating compositions are formulated by using as a reactive diluent, a low molecular weight hydroxyl-containing acrylic polymer. These polymers are prepared at about 15°-20° C. with anionic initiator concentrations greater than about 5 mole percent.
