144499-69-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144499-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,9 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144499-69:
(8*1)+(7*4)+(6*4)+(5*4)+(4*9)+(3*9)+(2*6)+(1*9)=164
164 % 10 = 4
So 144499-69-4 is a valid CAS Registry Number.
