Check Digit Verification of cas no

The CAS Registry Mumber 503156-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,1,5 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 503156-45:
(8*5)+(7*0)+(6*3)+(5*1)+(4*5)+(3*6)+(2*4)+(1*5)=114
114 % 10 = 4
So 503156-45-4 is a valid CAS Registry Number.
