27689-12-9 Usage
General Description
(1-methylethylidene)bis(4,1-phenyleneoxy-3,1-propanediyl) bismethacrylate, also known as Bisphenol A glycidyl methacrylate (BisGMA), is a chemical compound commonly used in the production of dental materials such as composite resins and adhesives. It is a dimethacrylate monomer that polymerizes into a highly cross-linked polymer, making it suitable for dental restorative applications. BisGMA is known for its high mechanical strength, good adhesion to tooth structure, and low polymerization shrinkage, making it a popular choice for dental materials. However, there is some concern about its potential endocrine-disrupting effects and toxicity, and further research is ongoing to determine its safety for use in dental applications.Check Digit Verification of cas no
The CAS Registry Mumber 27689-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,8 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.Calculate Digit Verification of CAS Registry Number 27689-12:
(7*2)+(6*7)+(5*6)+(4*8)+(3*9)+(2*1)+(1*2)=149
149 % 10 = 9
So 27689-12-9 is a valid CAS Registry Number.
