The CAS Registry Mumber 668-36-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 8 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 668-36: (5*6)+(4*6)+(3*8)+(2*3)+(1*6)=90 90 % 10 = 0 So 668-36-0 is a valid CAS Registry Number.
