Check Digit Verification of cas no

The CAS Registry Mumber 89357-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89357-25:
(7*8)+(6*9)+(5*3)+(4*5)+(3*7)+(2*2)+(1*5)=175
175 % 10 = 5
So 89357-25-5 is a valid CAS Registry Number.
