101842-61-9 Usage
General Description
"Hydroxyethyl methacrylate-methacrylic acid-ethyl methacrylate copolymer" is a copolymer, which means it is made from two or more different monomers. These monomers - hydroxyethyl methacrylate (HEMA), methacrylic acid and ethyl methacrylate, are combined in a process known as copolymerization. The properties of the resulting copolymer can vary greatly depending on the ratio and arrangement of the monomers. This particular copolymer is frequently used in medical applications due to its biocompatibility, such as in the composition of contact lenses and intraocular lenses. Furthermore, it is also used in drug delivery systems and coatings due to its hydrophilic properties. Low toxicity and good mechanical properties makes this copolymer a suitable material for various applications in the biomedical field.
Check Digit Verification of cas no
The CAS Registry Mumber 101842-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,8,4 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 101842-61:
(8*1)+(7*0)+(6*1)+(5*8)+(4*4)+(3*2)+(2*6)+(1*1)=89
89 % 10 = 9
So 101842-61-9 is a valid CAS Registry Number.
