Check Digit Verification of cas no

The CAS Registry Mumber 288607-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,6,0 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 288607-99:
(8*2)+(7*8)+(6*8)+(5*6)+(4*0)+(3*7)+(2*9)+(1*9)=198
198 % 10 = 8
So 288607-99-8 is a valid CAS Registry Number.
