Check Digit Verification of cas no

The CAS Registry Mumber 1189751-87-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,7,5 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1189751-87:
(9*1)+(8*1)+(7*8)+(6*9)+(5*7)+(4*5)+(3*1)+(2*8)+(1*7)=208
208 % 10 = 8
So 1189751-87-8 is a valid CAS Registry Number.
