Check Digit Verification of cas no

The CAS Registry Mumber 502916-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,9,1 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 502916-50:
(8*5)+(7*0)+(6*2)+(5*9)+(4*1)+(3*6)+(2*5)+(1*0)=129
129 % 10 = 9
So 502916-50-9 is a valid CAS Registry Number.
