144260-90-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144260-90-2 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, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144260-90:
(8*1)+(7*4)+(6*4)+(5*2)+(4*6)+(3*0)+(2*9)+(1*0)=112
112 % 10 = 2
So 144260-90-2 is a valid CAS Registry Number.
