Check Digit Verification of cas no
The CAS Registry Mumber 20513-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,1 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20513-43:
(7*2)+(6*0)+(5*5)+(4*1)+(3*3)+(2*4)+(1*3)=63
63 % 10 = 3
So 20513-43-3 is a valid CAS Registry Number.
