52724-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52724-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,7,2 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52724-28:
(7*5)+(6*2)+(5*7)+(4*2)+(3*4)+(2*2)+(1*8)=114
114 % 10 = 4
So 52724-28-4 is a valid CAS Registry Number.
