Check Digit Verification of cas no

The CAS Registry Mumber 439-09-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 439-09:
(5*4)+(4*3)+(3*9)+(2*0)+(1*9)=68
68 % 10 = 8
So 439-09-8 is a valid CAS Registry Number.
