The CAS Registry Mumber 5840-83-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,4 and 0 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5840-83: (6*5)+(5*8)+(4*4)+(3*0)+(2*8)+(1*3)=105 105 % 10 = 5 So 5840-83-5 is a valid CAS Registry Number.
