Check Digit Verification of cas no

The CAS Registry Mumber 503071-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,0,7 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 503071-72:
(8*5)+(7*0)+(6*3)+(5*0)+(4*7)+(3*1)+(2*7)+(1*2)=105
105 % 10 = 5
So 503071-72-5 is a valid CAS Registry Number.
