5023-02-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5023-02-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,2 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5023-02:
(6*5)+(5*0)+(4*2)+(3*3)+(2*0)+(1*2)=49
49 % 10 = 9
So 5023-02-9 is a valid CAS Registry Number.
