Check Digit Verification of cas no

The CAS Registry Mumber 288401-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,4,0 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 288401-68:
(8*2)+(7*8)+(6*8)+(5*4)+(4*0)+(3*1)+(2*6)+(1*8)=163
163 % 10 = 3
So 288401-68-3 is a valid CAS Registry Number.
