Check Digit Verification of cas no

The CAS Registry Mumber 25802-61-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,0 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25802-61:
(7*2)+(6*5)+(5*8)+(4*0)+(3*2)+(2*6)+(1*1)=103
103 % 10 = 3
So 25802-61-3 is a valid CAS Registry Number.
