General Description
Lead disulphide, also known as lead(II) sulfide, is a compound composed of lead and sulfur with the chemical formula PbS. It is a black solid with a metallic luster and is insoluble in water. Lead disulphide is commonly found in nature as the mineral galena and is a significant ore of lead. It is also used in the production of lead-acid batteries, infrared radiation detectors, and semiconductors. Lead disulphide is toxic and poses serious health risks if inhaled or ingested, as it can accumulate in the body over time and cause lead poisoning. Due to its toxicity, efforts are being made to limit its use and find safer alternatives.Check Digit Verification of cas no
The CAS Registry Mumber 12137-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,3 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.Calculate Digit Verification of CAS Registry Number 12137-74:
(7*1)+(6*2)+(5*1)+(4*3)+(3*7)+(2*7)+(1*4)=75
75 % 10 = 5
So 12137-74-5 is a valid CAS Registry Number.
