1404099-73-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1404099-73-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,4,0,9 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1404099-73:
(9*1)+(8*4)+(7*0)+(6*4)+(5*0)+(4*9)+(3*9)+(2*7)+(1*3)=145
145 % 10 = 5
So 1404099-73-5 is a valid CAS Registry Number.
