Check Digit Verification of cas no

The CAS Registry Mumber 84944-55-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,4 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 84944-55:
(7*8)+(6*4)+(5*9)+(4*4)+(3*4)+(2*5)+(1*5)=168
168 % 10 = 8
So 84944-55-8 is a valid CAS Registry Number.
