Check Digit Verification of cas no
The CAS Registry Mumber 98087-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,8 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98087-13:
(7*9)+(6*8)+(5*0)+(4*8)+(3*7)+(2*1)+(1*3)=169
169 % 10 = 9
