Check Digit Verification of cas no

The CAS Registry Mumber 89606-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,0 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89606-97:
(7*8)+(6*9)+(5*6)+(4*0)+(3*6)+(2*9)+(1*7)=183
183 % 10 = 3
So 89606-97-3 is a valid CAS Registry Number.
