α-Chlor-α-chlorsulfenyl-β-chlorpropiophenon, also known as CS gas, is a synthetic chemical compound primarily used as a riot control agent and tear gas. It is a colorless, oily liquid with a strong odor, and it is classified as a lachrymator, meaning it causes tearing and irritation in the eyes. CS gas works by causing severe eye pain, tearing, and temporary blindness, as well as respiratory issues such as coughing, choking, and difficulty breathing. It is widely used by law enforcement and military personnel for crowd control and to disperse protesters due to its non-lethal nature and relatively short-lasting effects. However, it is important to note that exposure to high concentrations of CS gas can lead to more serious health issues, and proper safety measures should be taken when handling or using this chemical.
The CAS Registry Mumber 31385-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,8 and 5 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 31385-53: (7*3)+(6*1)+(5*3)+(4*8)+(3*5)+(2*5)+(1*3)=102 102 % 10 = 2 So 31385-53-2 is a valid CAS Registry Number.
