Check Digit Verification of cas no

The CAS Registry Mumber 252913-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,9,1 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 252913-16:
(8*2)+(7*5)+(6*2)+(5*9)+(4*1)+(3*3)+(2*1)+(1*6)=129
129 % 10 = 9
So 252913-16-9 is a valid CAS Registry Number.
