144459-08-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144459-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,5 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 144459-08:
(8*1)+(7*4)+(6*4)+(5*4)+(4*5)+(3*9)+(2*0)+(1*8)=135
135 % 10 = 5
So 144459-08-5 is a valid CAS Registry Number.
