144176-45-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144176-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,7 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 144176-45:
(8*1)+(7*4)+(6*4)+(5*1)+(4*7)+(3*6)+(2*4)+(1*5)=124
124 % 10 = 4
So 144176-45-4 is a valid CAS Registry Number.
