94853-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94853-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,8,5 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 94853-57:
(7*9)+(6*4)+(5*8)+(4*5)+(3*3)+(2*5)+(1*7)=173
173 % 10 = 3
So 94853-57-3 is a valid CAS Registry Number.
