Check Digit Verification of cas no

The CAS Registry Mumber 854020-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,0,2 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 854020-54:
(8*8)+(7*5)+(6*4)+(5*0)+(4*2)+(3*0)+(2*5)+(1*4)=145
145 % 10 = 5
So 854020-54-5 is a valid CAS Registry Number.
