684-82-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 684-82-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 684-82:
(5*6)+(4*8)+(3*4)+(2*8)+(1*2)=92
92 % 10 = 2
So 684-82-2 is a valid CAS Registry Number.
