Check Digit Verification of cas no

The CAS Registry Mumber 408358-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,8,3,5 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 408358-03:
(8*4)+(7*0)+(6*8)+(5*3)+(4*5)+(3*8)+(2*0)+(1*3)=142
142 % 10 = 2
So 408358-03-2 is a valid CAS Registry Number.
