Check Digit Verification of cas no

The CAS Registry Mumber 25513-64-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,1 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25513-64:
(7*2)+(6*5)+(5*5)+(4*1)+(3*3)+(2*6)+(1*4)=98
98 % 10 = 8
So 25513-64-8 is a valid CAS Registry Number.
