1440419-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1440419-83-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,4,1 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1440419-83:
(9*1)+(8*4)+(7*4)+(6*0)+(5*4)+(4*1)+(3*9)+(2*8)+(1*3)=139
139 % 10 = 9
So 1440419-83-9 is a valid CAS Registry Number.
