84040-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84040-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,4 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84040-49:
(7*8)+(6*4)+(5*0)+(4*4)+(3*0)+(2*4)+(1*9)=113
113 % 10 = 3
So 84040-49-3 is a valid CAS Registry Number.
