Check Digit Verification of cas no

The CAS Registry Mumber 254-83-1 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, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 254-83:
(5*2)+(4*5)+(3*4)+(2*8)+(1*3)=61
61 % 10 = 1
So 254-83-1 is a valid CAS Registry Number.
