Bis(methoxycarbonyl)sulfide, also known as carbonyl sulfide or COS, is a colorless, toxic gas with the chemical formula OCS. It is an important intermediate in the chemical industry, used in the production of various chemicals, including thiophosphates, dithiocarbamates, and carbon disulfide. COS is also a naturally occurring compound, released by plants and animals, and plays a role in the Earth's atmosphere. It is a byproduct of various industrial processes, such as the production of ethylene and the combustion of fossil fuels. Due to its potential environmental and health impacts, efforts are being made to reduce its emissions and develop more efficient methods for its capture and utilization.
The CAS Registry Mumber 1190-35-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 0 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1190-35: (6*1)+(5*1)+(4*9)+(3*0)+(2*3)+(1*5)=58 58 % 10 = 8 So 1190-35-8 is a valid CAS Registry Number.
