Check Digit Verification of cas no

The CAS Registry Mumber 89291-07-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,9 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89291-07:
(7*8)+(6*9)+(5*2)+(4*9)+(3*1)+(2*0)+(1*7)=166
166 % 10 = 6
So 89291-07-6 is a valid CAS Registry Number.
