6296-57-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6296-57-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,9 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6296-57:
(6*6)+(5*2)+(4*9)+(3*6)+(2*5)+(1*7)=117
117 % 10 = 7
So 6296-57-7 is a valid CAS Registry Number.
