Check Digit Verification of cas no

The CAS Registry Mumber 425619-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,5,6,1 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 425619-08:
(8*4)+(7*2)+(6*5)+(5*6)+(4*1)+(3*9)+(2*0)+(1*8)=145
145 % 10 = 5
So 425619-08-5 is a valid CAS Registry Number.
