5453-00-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5453-00-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,5 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5453-00:
(6*5)+(5*4)+(4*5)+(3*3)+(2*0)+(1*0)=79
79 % 10 = 9
So 5453-00-9 is a valid CAS Registry Number.
