Check Digit Verification of cas no

The CAS Registry Mumber 5120-39-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,2 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5120-39:
(6*5)+(5*1)+(4*2)+(3*0)+(2*3)+(1*9)=58
58 % 10 = 8
So 5120-39-8 is a valid CAS Registry Number.
