4854-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4854-57-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,5 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4854-57:
(6*4)+(5*8)+(4*5)+(3*4)+(2*5)+(1*7)=113
113 % 10 = 3
So 4854-57-3 is a valid CAS Registry Number.
