Check Digit Verification of cas no

The CAS Registry Mumber 181259-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,2,5 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 181259-90:
(8*1)+(7*8)+(6*1)+(5*2)+(4*5)+(3*9)+(2*9)+(1*0)=145
145 % 10 = 5
So 181259-90-5 is a valid CAS Registry Number.
