5304-74-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5304-74-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,0 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5304-74:
(6*5)+(5*3)+(4*0)+(3*4)+(2*7)+(1*4)=75
75 % 10 = 5
So 5304-74-5 is a valid CAS Registry Number.
