Check Digit Verification of cas no

The CAS Registry Mumber 128980-84-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,8 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128980-84:
(8*1)+(7*2)+(6*8)+(5*9)+(4*8)+(3*0)+(2*8)+(1*4)=167
167 % 10 = 7
So 128980-84-7 is a valid CAS Registry Number.
