534569-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 534569-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,4,5,6 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 534569-45:
(8*5)+(7*3)+(6*4)+(5*5)+(4*6)+(3*9)+(2*4)+(1*5)=174
174 % 10 = 4
So 534569-45-4 is a valid CAS Registry Number.
