4203-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4203-40-1 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, 4 and 0 respectively.Calculate Digit Verification of CAS Registry Number 4203-40:
(6*4)+(5*2)+(4*0)+(3*3)+(2*4)+(1*0)=51
51 % 10 = 1
So 4203-40-1 is a valid CAS Registry Number.
