Check Digit Verification of cas no

The CAS Registry Mumber 128677-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,7 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128677-84:
(8*1)+(7*2)+(6*8)+(5*6)+(4*7)+(3*7)+(2*8)+(1*4)=169
169 % 10 = 9
So 128677-84-9 is a valid CAS Registry Number.
