Check Digit Verification of cas no

The CAS Registry Mumber 872529-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,5,2 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 872529-04:
(8*8)+(7*7)+(6*2)+(5*5)+(4*2)+(3*9)+(2*0)+(1*4)=189
189 % 10 = 9
So 872529-04-9 is a valid CAS Registry Number.
