Check Digit Verification of cas no
The CAS Registry Mumber 548-80-1 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 0 respectively.
Calculate Digit Verification of CAS Registry Number 548-80:
(5*5)+(4*4)+(3*8)+(2*8)+(1*0)=81
81 % 10 = 1
So 548-80-1 is a valid CAS Registry Number.
