51297-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51297-25-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,2,9 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 51297-25:
(7*5)+(6*1)+(5*2)+(4*9)+(3*7)+(2*2)+(1*5)=117
117 % 10 = 7
So 51297-25-7 is a valid CAS Registry Number.
