82257-56-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82257-56-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,5 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.Calculate Digit Verification of CAS Registry Number 82257-56:
(7*8)+(6*2)+(5*2)+(4*5)+(3*7)+(2*5)+(1*6)=135
135 % 10 = 5
So 82257-56-5 is a valid CAS Registry Number.
