4499-39-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4499-39-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,9 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4499-39:
(6*4)+(5*4)+(4*9)+(3*9)+(2*3)+(1*9)=122
122 % 10 = 2
So 4499-39-2 is a valid CAS Registry Number.
