545400-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 545400-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,5,4,0 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 545400-04:
(8*5)+(7*4)+(6*5)+(5*4)+(4*0)+(3*0)+(2*0)+(1*4)=122
122 % 10 = 2
So 545400-04-2 is a valid CAS Registry Number.
