144125-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144125-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,2 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144125-89:
(8*1)+(7*4)+(6*4)+(5*1)+(4*2)+(3*5)+(2*8)+(1*9)=113
113 % 10 = 3
So 144125-89-3 is a valid CAS Registry Number.
