Check Digit Verification of cas no

The CAS Registry Mumber 5112-90-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,1 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5112-90:
(6*5)+(5*1)+(4*1)+(3*2)+(2*9)+(1*0)=63
63 % 10 = 3
So 5112-90-3 is a valid CAS Registry Number.
