The CAS Registry Mumber 3898-93-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,9 and 8 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3898-93: (6*3)+(5*8)+(4*9)+(3*8)+(2*9)+(1*3)=139 139 % 10 = 9 So 3898-93-9 is a valid CAS Registry Number.
