144260-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144260-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,6 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144260-89:
(8*1)+(7*4)+(6*4)+(5*2)+(4*6)+(3*0)+(2*8)+(1*9)=119
119 % 10 = 9
So 144260-89-9 is a valid CAS Registry Number.
