4296-42-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4296-42-8 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 6 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 4296-42:
(6*4)+(5*2)+(4*9)+(3*6)+(2*4)+(1*2)=98
98 % 10 = 8
So 4296-42-8 is a valid CAS Registry Number.
