4297-94-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4297-94-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,9 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4297-94:
(6*4)+(5*2)+(4*9)+(3*7)+(2*9)+(1*4)=113
113 % 10 = 3
So 4297-94-3 is a valid CAS Registry Number.
