144584-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144584-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,5,8 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 144584-42:
(8*1)+(7*4)+(6*4)+(5*5)+(4*8)+(3*4)+(2*4)+(1*2)=139
139 % 10 = 9
So 144584-42-9 is a valid CAS Registry Number.
