54702-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54702-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,7,0 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 54702-45:
(7*5)+(6*4)+(5*7)+(4*0)+(3*2)+(2*4)+(1*5)=113
113 % 10 = 3
So 54702-45-3 is a valid CAS Registry Number.
