Check Digit Verification of cas no
The CAS Registry Mumber 18813-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,1 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18813-28:
(7*1)+(6*8)+(5*8)+(4*1)+(3*3)+(2*2)+(1*8)=120
120 % 10 = 0
So 18813-28-0 is a valid CAS Registry Number.
