Check Digit Verification of cas no

The CAS Registry Mumber 1198005-64-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,0,0 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1198005-64:
(9*1)+(8*1)+(7*9)+(6*8)+(5*0)+(4*0)+(3*5)+(2*6)+(1*4)=159
159 % 10 = 9
So 1198005-64-9 is a valid CAS Registry Number.
