Check Digit Verification of cas no

The CAS Registry Mumber 548-81-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 548-81:
(5*5)+(4*4)+(3*8)+(2*8)+(1*1)=82
82 % 10 = 2
So 548-81-2 is a valid CAS Registry Number.
