Check Digit Verification of cas no

The CAS Registry Mumber 5839-69-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,3 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5839-69:
(6*5)+(5*8)+(4*3)+(3*9)+(2*6)+(1*9)=130
130 % 10 = 0
So 5839-69-0 is a valid CAS Registry Number.
