596-04-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 596-04-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 596-04:
(5*5)+(4*9)+(3*6)+(2*0)+(1*4)=83
83 % 10 = 3
So 596-04-3 is a valid CAS Registry Number.
