Check Digit Verification of cas no

The CAS Registry Mumber 89921-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,2 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89921-31:
(7*8)+(6*9)+(5*9)+(4*2)+(3*1)+(2*3)+(1*1)=173
173 % 10 = 3
So 89921-31-3 is a valid CAS Registry Number.
