The CAS Registry Mumber 98006-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,0 and 6 respectively; the second part has 2 digits, 1 and 3 respectively. Calculate Digit Verification of CAS Registry Number 98006-13: (7*9)+(6*8)+(5*0)+(4*0)+(3*6)+(2*1)+(1*3)=134 134 % 10 = 4 So 98006-13-4 is a valid CAS Registry Number.
