Check Digit Verification of cas no

The CAS Registry Mumber 255-01-6 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 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 255-01:
(5*2)+(4*5)+(3*5)+(2*0)+(1*1)=46
46 % 10 = 6
So 255-01-6 is a valid CAS Registry Number.
