721-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 721-53-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.Calculate Digit Verification of CAS Registry Number 721-53:
(5*7)+(4*2)+(3*1)+(2*5)+(1*3)=59
59 % 10 = 9
So 721-53-9 is a valid CAS Registry Number.
