Check Digit Verification of cas no
The CAS Registry Mumber 6980-13-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,8 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6980-13:
(6*6)+(5*9)+(4*8)+(3*0)+(2*1)+(1*3)=118
118 % 10 = 8
