Check Digit Verification of cas no

The CAS Registry Mumber 181587-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,5,8 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 181587-51:
(8*1)+(7*8)+(6*1)+(5*5)+(4*8)+(3*7)+(2*5)+(1*1)=159
159 % 10 = 9
So 181587-51-9 is a valid CAS Registry Number.
