70293-55-9 Usage
Uses
4-META can be used in the formation of resin to fix the vertical root fracture by root fragment bonding.
General Description
4-Methacryloxyethyl trimellitic anhydride (4-META), a widely used dental adhesive, improves the bond strength between the metal and acrylic resin. It has an anhydride group that bonds with dental metal substrates and the methacrylate group that polymerizes and copolymerizes with monomeric composite resin.
Check Digit Verification of cas no
The CAS Registry Mumber 70293-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,9 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70293-55:
(7*7)+(6*0)+(5*2)+(4*9)+(3*3)+(2*5)+(1*5)=119
119 % 10 = 9
So 70293-55-9 is a valid CAS Registry Number.
