Sodium phosphite, with the chemical formula Na2HPO3, is a white, crystalline compound consisting of sodium cations and phosphite anions. It is recognized for its utility as a reducing agent in organic synthesis and as a phosphorus source in fertilizers and agricultural applications. Additionally, it finds use in electroplating and as a stabilizer in plastics and polymers. Despite its relatively non-toxic nature, which allows for some applications in food and pharmaceuticals, it requires careful handling to prevent skin, eye, and respiratory irritation, as well as potential harm from ingestion or inhalation.

Check Digit Verification of cas no

The CAS Registry Mumber 15475-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,4,7 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 15475-67:
(7*1)+(6*5)+(5*4)+(4*7)+(3*5)+(2*6)+(1*7)=119
119 % 10 = 9
So 15475-67-9 is a valid CAS Registry Number.
