Check Digit Verification of cas no

The CAS Registry Mumber 183251-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,2,5 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 183251-70:
(8*1)+(7*8)+(6*3)+(5*2)+(4*5)+(3*1)+(2*7)+(1*0)=129
129 % 10 = 9
So 183251-70-9 is a valid CAS Registry Number.
