Check Digit Verification of cas no

The CAS Registry Mumber 72409-25-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,4,0 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72409-25:
(7*7)+(6*2)+(5*4)+(4*0)+(3*9)+(2*2)+(1*5)=117
117 % 10 = 7
So 72409-25-7 is a valid CAS Registry Number.
