Check Digit Verification of cas no

The CAS Registry Mumber 25459-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,5 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25459-12:
(7*2)+(6*5)+(5*4)+(4*5)+(3*9)+(2*1)+(1*2)=115
115 % 10 = 5
So 25459-12-5 is a valid CAS Registry Number.
