The CAS Registry Mumber 982-82-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,8 and 2 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 982-82: (5*9)+(4*8)+(3*2)+(2*8)+(1*2)=101 101 % 10 = 1 So 982-82-1 is a valid CAS Registry Number.
