DOWEX-50W-HYDROGEN is a cation exchange resin produced by Dow Chemical Company, specifically designed for use in water softening and demineralization processes. This resin is in its hydrogen form, which means it has been pre-conditioned with a hydrogen solution, making it ready for immediate use in applications such as water treatment and purification. It is known for its high capacity, selectivity, and fast kinetics, which contribute to its effectiveness in removing cationic impurities from water. The resin's spherical, macroporous structure allows for efficient ion exchange, making it suitable for various industrial and commercial applications where water quality is critical.
The CAS Registry Mumber 9051-01-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,5 and 1 respectively; the second part has 2 digits, 0 and 1 respectively. Calculate Digit Verification of CAS Registry Number 9051-01: (6*9)+(5*0)+(4*5)+(3*1)+(2*0)+(1*1)=78 78 % 10 = 8 So 9051-01-8 is a valid CAS Registry Number.
