Check Digit Verification of cas no

The CAS Registry Mumber 1189562-07-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,5,6 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1189562-07:
(9*1)+(8*1)+(7*8)+(6*9)+(5*5)+(4*6)+(3*2)+(2*0)+(1*7)=189
189 % 10 = 9
So 1189562-07-9 is a valid CAS Registry Number.
