54837-18-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54837-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,3 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54837-18:
(7*5)+(6*4)+(5*8)+(4*3)+(3*7)+(2*1)+(1*8)=142
142 % 10 = 2
So 54837-18-2 is a valid CAS Registry Number.
