Check Digit Verification of cas no
The CAS Registry Mumber 468-28-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 468-28:
(5*4)+(4*6)+(3*8)+(2*2)+(1*8)=80
80 % 10 = 0
So 468-28-0 is a valid CAS Registry Number.
