The CAS Registry Mumber 1698-79-9 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 8 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1698-79: (6*1)+(5*6)+(4*9)+(3*8)+(2*7)+(1*9)=119 119 % 10 = 9 So 1698-79-9 is a valid CAS Registry Number.
