The CAS Registry Mumber 1697-13-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 7 respectively; the second part has 2 digits, 1 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1697-13: (6*1)+(5*6)+(4*9)+(3*7)+(2*1)+(1*3)=98 98 % 10 = 8 So 1697-13-8 is a valid CAS Registry Number.
