4301-02-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4301-02-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,0 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4301-02:
(6*4)+(5*3)+(4*0)+(3*1)+(2*0)+(1*2)=44
44 % 10 = 4
So 4301-02-4 is a valid CAS Registry Number.
