3840-05-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3840-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,4 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3840-05:
(6*3)+(5*8)+(4*4)+(3*0)+(2*0)+(1*5)=79
79 % 10 = 9
So 3840-05-9 is a valid CAS Registry Number.
