Check Digit Verification of cas no

The CAS Registry Mumber 159557-87-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,5,5 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 159557-87:
(8*1)+(7*5)+(6*9)+(5*5)+(4*5)+(3*7)+(2*8)+(1*7)=186
186 % 10 = 6
So 159557-87-6 is a valid CAS Registry Number.
