Check Digit Verification of cas no

The CAS Registry Mumber 889109-12-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,1,0 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 889109-12:
(8*8)+(7*8)+(6*9)+(5*1)+(4*0)+(3*9)+(2*1)+(1*2)=210
210 % 10 = 0
So 889109-12-0 is a valid CAS Registry Number.
