The CAS Registry Mumber 698-62-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 8 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 698-62: (5*6)+(4*9)+(3*8)+(2*6)+(1*2)=104 104 % 10 = 4 So 698-62-4 is a valid CAS Registry Number.
