4209-03-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4209-03-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4209-03:
(6*4)+(5*2)+(4*0)+(3*9)+(2*0)+(1*3)=64
64 % 10 = 4
So 4209-03-4 is a valid CAS Registry Number.
