The CAS Registry Mumber 563-86-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 3 respectively; the second part has 2 digits, 8 and 6 respectively. Calculate Digit Verification of CAS Registry Number 563-86: (5*5)+(4*6)+(3*3)+(2*8)+(1*6)=80 80 % 10 = 0 So 563-86-0 is a valid CAS Registry Number.
