Check Digit Verification of cas no

The CAS Registry Mumber 148918-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,9,1 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 148918-02:
(8*1)+(7*4)+(6*8)+(5*9)+(4*1)+(3*8)+(2*0)+(1*2)=159
159 % 10 = 9
So 148918-02-9 is a valid CAS Registry Number.
