144346-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144346-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,4 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144346-53:
(8*1)+(7*4)+(6*4)+(5*3)+(4*4)+(3*6)+(2*5)+(1*3)=122
122 % 10 = 2
So 144346-53-2 is a valid CAS Registry Number.
