N-(4-Chlorphenyl)-N'-methylsulfonyl-guanidin, also known as Chlorsulfonyl or CS gas, is a chemical compound with the formula C7H7ClN2O2S. It is a colorless, oily liquid that is highly volatile and has a pungent odor. CS gas is primarily used as a riot control agent due to its ability to cause severe irritation to the eyes, respiratory system, and skin when inhaled or exposed to. It is synthesized by reacting 4-chloroaniline with methylsulfonyl chloride and then with guanidine. CS gas is classified as a lachrymator, meaning it causes tearing and pain in the eyes, and is used by law enforcement and military personnel to disperse crowds and control civil disturbances. It is considered less harmful than other tear gases like CN or CR, as its effects are temporary and do not cause permanent damage when used in appropriate concentrations.

Check Digit Verification of cas no
The CAS Registry Mumber 5740-09-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,4 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.Calculate Digit Verification of CAS Registry Number 5740-09:
(6*5)+(5*7)+(4*4)+(3*0)+(2*0)+(1*9)=90
90 % 10 = 0
So 5740-09-0 is a valid CAS Registry Number.
