4743-96-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4743-96-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.Calculate Digit Verification of CAS Registry Number 4743-96:
(6*4)+(5*7)+(4*4)+(3*3)+(2*9)+(1*6)=108
108 % 10 = 8
So 4743-96-8 is a valid CAS Registry Number.
