Check Digit Verification of cas no

The CAS Registry Mumber 109889-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,8 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109889-85:
(8*1)+(7*0)+(6*9)+(5*8)+(4*8)+(3*9)+(2*8)+(1*5)=182
182 % 10 = 2
So 109889-85-2 is a valid CAS Registry Number.
