4203-26-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4203-26-3 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 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4203-26:
(6*4)+(5*2)+(4*0)+(3*3)+(2*2)+(1*6)=53
53 % 10 = 3
So 4203-26-3 is a valid CAS Registry Number.
