2548-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2548-39-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,4 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.Calculate Digit Verification of CAS Registry Number 2548-39:
(6*2)+(5*5)+(4*4)+(3*8)+(2*3)+(1*9)=92
92 % 10 = 2
So 2548-39-2 is a valid CAS Registry Number.
