Check Digit Verification of cas no

The CAS Registry Mumber 412028-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,2,0,2 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 412028-14:
(8*4)+(7*1)+(6*2)+(5*0)+(4*2)+(3*8)+(2*1)+(1*4)=89
89 % 10 = 9
So 412028-14-9 is a valid CAS Registry Number.
