Check Digit Verification of cas no

The CAS Registry Mumber 128685-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,8 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128685-90:
(8*1)+(7*2)+(6*8)+(5*6)+(4*8)+(3*5)+(2*9)+(1*0)=165
165 % 10 = 5
So 128685-90-5 is a valid CAS Registry Number.
