Check Digit Verification of cas no

The CAS Registry Mumber 254-18-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 254-18:
(5*2)+(4*5)+(3*4)+(2*1)+(1*8)=52
52 % 10 = 2
So 254-18-2 is a valid CAS Registry Number.
