Check Digit Verification of cas no

The CAS Registry Mumber 25570-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,7 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25570-64:
(7*2)+(6*5)+(5*5)+(4*7)+(3*0)+(2*6)+(1*4)=113
113 % 10 = 3
So 25570-64-3 is a valid CAS Registry Number.
