72257-25-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72257-25-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72257-25:
(7*7)+(6*2)+(5*2)+(4*5)+(3*7)+(2*2)+(1*5)=121
121 % 10 = 1
So 72257-25-1 is a valid CAS Registry Number.
