Tris(hydroxymethyl)phosphine sulfide, also known as THPS or PHOST, is a chemical compound with the formula (HOCH2)3PS. It is a colorless, water-soluble liquid that is widely used as a biocide in various industrial applications, particularly in the oil and gas industry. THPS is effective in controlling the growth of sulfate-reducing bacteria (SRB) and other microorganisms that can cause corrosion and biofouling in pipelines and storage tanks. It is also used in cooling water systems, paper mills, and other industrial processes where microbial control is necessary. The compound works by disrupting the cell membranes of bacteria, leading to their death. THPS is considered less toxic and more environmentally friendly compared to some other biocides, making it a preferred choice in many applications.

Check Digit Verification of cas no

The CAS Registry Mumber 1067-13-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,6 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1067-13:
(6*1)+(5*0)+(4*6)+(3*7)+(2*1)+(1*3)=56
56 % 10 = 6
So 1067-13-6 is a valid CAS Registry Number.
