Check Digit Verification of cas no

The CAS Registry Mumber 503112-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,1,1 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 503112-05:
(8*5)+(7*0)+(6*3)+(5*1)+(4*1)+(3*2)+(2*0)+(1*5)=78
78 % 10 = 8
So 503112-05-8 is a valid CAS Registry Number.
