540519-19-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 540519-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,0,5,1 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 540519-19:
(8*5)+(7*4)+(6*0)+(5*5)+(4*1)+(3*9)+(2*1)+(1*9)=135
135 % 10 = 5
So 540519-19-5 is a valid CAS Registry Number.
