4909-42-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4909-42-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,0 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 4909-42:
(6*4)+(5*9)+(4*0)+(3*9)+(2*4)+(1*2)=106
106 % 10 = 6
So 4909-42-6 is a valid CAS Registry Number.
