Check Digit Verification of cas no

The CAS Registry Mumber 2581-85-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,8 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2581-85:
(6*2)+(5*5)+(4*8)+(3*1)+(2*8)+(1*5)=93
93 % 10 = 3
So 2581-85-3 is a valid CAS Registry Number.
