4542-82-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4542-82-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4542-82:
(6*4)+(5*5)+(4*4)+(3*2)+(2*8)+(1*2)=89
89 % 10 = 9
So 4542-82-9 is a valid CAS Registry Number.
