Check Digit Verification of cas no

The CAS Registry Mumber 149490-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,4,9 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 149490-95:
(8*1)+(7*4)+(6*9)+(5*4)+(4*9)+(3*0)+(2*9)+(1*5)=169
169 % 10 = 9
