Check Digit Verification of cas no

The CAS Registry Mumber 881677-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,6,7 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 881677-97:
(8*8)+(7*8)+(6*1)+(5*6)+(4*7)+(3*7)+(2*9)+(1*7)=230
230 % 10 = 0
So 881677-97-0 is a valid CAS Registry Number.
