Check Digit Verification of cas no

The CAS Registry Mumber 28910-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,9,1 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28910-89:
(7*2)+(6*8)+(5*9)+(4*1)+(3*0)+(2*8)+(1*9)=136
136 % 10 = 6
So 28910-89-6 is a valid CAS Registry Number.
