40090-76-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40090-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,9 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40090-76:
(7*4)+(6*0)+(5*0)+(4*9)+(3*0)+(2*7)+(1*6)=84
84 % 10 = 4
So 40090-76-4 is a valid CAS Registry Number.
