39257-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39257-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,5 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 39257-53:
(7*3)+(6*9)+(5*2)+(4*5)+(3*7)+(2*5)+(1*3)=139
139 % 10 = 9
So 39257-53-9 is a valid CAS Registry Number.
