Check Digit Verification of cas no

The CAS Registry Mumber 1171887-56-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,1,8,8 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1171887-56:
(9*1)+(8*1)+(7*7)+(6*1)+(5*8)+(4*8)+(3*7)+(2*5)+(1*6)=181
181 % 10 = 1
So 1171887-56-1 is a valid CAS Registry Number.
