Mustard gas was first used in World War I and remains a significant concern in the context of chemical warfare due to its persistence and severe health impacts.
The CAS Registry Mumber 675-91-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 5 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 675-91: (5*6)+(4*7)+(3*5)+(2*9)+(1*1)=92 92 % 10 = 2 So 675-91-2 is a valid CAS Registry Number.
