Check Digit Verification of cas no

The CAS Registry Mumber 2509-16-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,0 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2509-16:
(6*2)+(5*5)+(4*0)+(3*9)+(2*1)+(1*6)=72
72 % 10 = 2
So 2509-16-2 is a valid CAS Registry Number.
