Check Digit Verification of cas no

The CAS Registry Mumber 1181643-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,1,6,4 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1181643-89:
(9*1)+(8*1)+(7*8)+(6*1)+(5*6)+(4*4)+(3*3)+(2*8)+(1*9)=159
159 % 10 = 9
So 1181643-89-9 is a valid CAS Registry Number.
