5463-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5463-54-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,6 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5463-54:
(6*5)+(5*4)+(4*6)+(3*3)+(2*5)+(1*4)=97
97 % 10 = 7
So 5463-54-7 is a valid CAS Registry Number.
