106899-94-9 Usage
General Description
Poly(ethyleneimine) (PEI) is a synthetic polymer that is commonly used in various industrial and commercial applications. It is a cationic polymer with a high molecular weight and a high charge density, making it useful as a flocculant in water treatment, as a binder in paper and textiles, and as a coating for various surfaces. PEI is also used in biomedical and pharmaceutical applications, including gene therapy and drug delivery, due to its ability to form complexes with nucleic acids and proteins. Additionally, it is employed in the production of resins, adhesives, and coatings, as well as in the manufacture of nanoparticles and nanocomposites. However, PEI can be toxic in high concentrations, so proper handling and disposal are essential to prevent harm to human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 106899-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,8,9 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 106899-94:
(8*1)+(7*0)+(6*6)+(5*8)+(4*9)+(3*9)+(2*9)+(1*4)=169
169 % 10 = 9
So 106899-94-9 is a valid CAS Registry Number.
