1440419-94-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1440419-94-2 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, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1440419-94:
(9*1)+(8*4)+(7*4)+(6*0)+(5*4)+(4*1)+(3*9)+(2*9)+(1*4)=142
142 % 10 = 2
So 1440419-94-2 is a valid CAS Registry Number.
