75228-55-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75228-55-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,2 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 75228-55:
(7*7)+(6*5)+(5*2)+(4*2)+(3*8)+(2*5)+(1*5)=136
136 % 10 = 6
So 75228-55-6 is a valid CAS Registry Number.
