The CAS Registry Mumber 89908-85-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,0 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89908-85:
(7*8)+(6*9)+(5*9)+(4*0)+(3*8)+(2*8)+(1*5)=200
200 % 10 = 0
