Check Digit Verification of cas no
The CAS Registry Mumber 20544-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,4 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20544-45:
(7*2)+(6*0)+(5*5)+(4*4)+(3*4)+(2*4)+(1*5)=80
80 % 10 = 0
So 20544-45-0 is a valid CAS Registry Number.
