25766-59-0 Usage
General Description
Polycarbonate resins are a type of thermoplastic polymer that combines high impact resistance, high heat resistance, and optical clarity. These transparent plastics are mainly composed of Carbon, Hydrogen, and Oxygen atoms in a recurring pattern. Polycarbonate resins are used extensively in applications that require durability and resistance to forced entry, such as safety glasses, security windows, riot shields, DVDs, CDs, and even in medical applications. This material is also quite reactive, which is why it can be easily combined with flame retardants and other additives, making it more versatile. Despite their many advantages, their main disadvantage is poor resistance to alkalis and active hydrocarbons.
Check Digit Verification of cas no
The CAS Registry Mumber 25766-59-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,6 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25766-59:
(7*2)+(6*5)+(5*7)+(4*6)+(3*6)+(2*5)+(1*9)=140
140 % 10 = 0
So 25766-59-0 is a valid CAS Registry Number.
