Check Digit Verification of cas no

The CAS Registry Mumber 24448-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,4 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 24448-20:
(7*2)+(6*4)+(5*4)+(4*4)+(3*8)+(2*2)+(1*0)=102
102 % 10 = 2
So 24448-20-2 is a valid CAS Registry Number.

METHOD FOR THE PRODUCTION OF (METH)ACRYLIC ESTERS

-

Page/Page column 6, (2011/06/23)

The present invention relates to a process for preparing (meth)acrylates, comprising the transesterification of a low-boiling ester of (meth)acrylic acid with a reactant alcohol in the presence of catalysts, which is characterized in that the transesterification is catalysed by a basic ion exchanger.

DENTAL COMPOSITION AND COMPOSITE RESIN

-

, (2011/02/18)

A dental composition of the present invention includes: a polymerizable monomer component (A); and an amorphous filler (B) having an average particle size of 1 to 20 μm and including silica-based fine particles and coatings of an oxide that cover the surfaces of the silica-based fine particles. The oxide contains a zirconium atom, a silicon atom, and an oxygen atom. The dental composition contains 20 to 500 parts by weight of the filler (B) per 100 parts by weight of the polymerizable monomer component (A). The dental composition has a viscosity of 10 to 800 Pa·s. It is preferable that the filler (B) contain spherical particles, and that the percentage of the spherical particles in the filler (B) be at least 60%.
