AMBERLITE(R) IRA-938 is a high-performance, macroreticular, strongly basic anion exchange resin produced by the Rohm and Haas Company. It is designed for applications requiring high selectivity and capacity for specific anions, such as nitrate removal from drinking water, sugar demineralization, and pharmaceutical processes. The resin's structure consists of a polystyrene matrix with quaternary ammonium functional groups, which provide excellent chemical and physical stability, allowing it to operate effectively in a wide range of conditions. AMBERLITE(R) IRA-938 is known for its high selectivity towards target anions, fast exchange kinetics, and low pressure drop, making it a popular choice in various industrial and environmental applications.
The CAS Registry Mumber 52932-61-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,9,3 and 2 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 52932-61: (7*5)+(6*2)+(5*9)+(4*3)+(3*2)+(2*6)+(1*1)=123 123 % 10 = 3 So 52932-61-3 is a valid CAS Registry Number.
