Check Digit Verification of cas no

The CAS Registry Mumber 89614-16-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,1 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89614-16:
(7*8)+(6*9)+(5*6)+(4*1)+(3*4)+(2*1)+(1*6)=164
164 % 10 = 4
So 89614-16-4 is a valid CAS Registry Number.
