7253-04-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7253-04-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,5 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7253-04:
(6*7)+(5*2)+(4*5)+(3*3)+(2*0)+(1*4)=85
85 % 10 = 5
So 7253-04-5 is a valid CAS Registry Number.
