Check Digit Verification of cas no

The CAS Registry Mumber 1089-80-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,8 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1089-80:
(6*1)+(5*0)+(4*8)+(3*9)+(2*8)+(1*0)=81
81 % 10 = 1
So 1089-80-1 is a valid CAS Registry Number.
