2581-45-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2581-45-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,8 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2581-45:
(6*2)+(5*5)+(4*8)+(3*1)+(2*4)+(1*5)=85
85 % 10 = 5
So 2581-45-5 is a valid CAS Registry Number.
