Check Digit Verification of cas no

The CAS Registry Mumber 861220-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,2,2 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 861220-75:
(8*8)+(7*6)+(6*1)+(5*2)+(4*2)+(3*0)+(2*7)+(1*5)=149
149 % 10 = 9
So 861220-75-9 is a valid CAS Registry Number.
