Check Digit Verification of cas no
The CAS Registry Mumber 200813-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,8,1 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 200813-55:
(8*2)+(7*0)+(6*0)+(5*8)+(4*1)+(3*3)+(2*5)+(1*5)=84
84 % 10 = 4
So 200813-55-4 is a valid CAS Registry Number.
