290-04-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 290-04-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 290-04:
(5*2)+(4*9)+(3*0)+(2*0)+(1*4)=50
50 % 10 = 0
So 290-04-0 is a valid CAS Registry Number.
