Monosulph, also known as monosodium sulfide (Na2S), is a chemical compound that consists of sodium and sulfide ions. It is a white, water-soluble solid with a strong odor and is commonly used in various industrial applications, such as water treatment, paper manufacturing, and textile processing. Monosulph is effective in controlling hydrogen sulfide and odor issues, as well as reducing heavy metals and other contaminants. It is also employed in the production of dyes, tanning agents, and pharmaceuticals. Due to its reactivity, it is essential to handle and store monosulph carefully, following proper safety guidelines.
The CAS Registry Mumber 8039-98-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,3 and 9 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 8039-98: (6*8)+(5*0)+(4*3)+(3*9)+(2*9)+(1*8)=113 113 % 10 = 3 So 8039-98-3 is a valid CAS Registry Number.
