144899-50-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144899-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,9 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144899-50:
(8*1)+(7*4)+(6*4)+(5*8)+(4*9)+(3*9)+(2*5)+(1*0)=173
173 % 10 = 3
So 144899-50-3 is a valid CAS Registry Number.
