257-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 257-99-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 257-99:
(5*2)+(4*5)+(3*7)+(2*9)+(1*9)=78
78 % 10 = 8
So 257-99-8 is a valid CAS Registry Number.
