52128-53-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52128-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,2 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.Calculate Digit Verification of CAS Registry Number 52128-53:
(7*5)+(6*2)+(5*1)+(4*2)+(3*8)+(2*5)+(1*3)=97
97 % 10 = 7
So 52128-53-7 is a valid CAS Registry Number.
