14494-93-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14494-93-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,4,9 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 14494-93:
(7*1)+(6*4)+(5*4)+(4*9)+(3*4)+(2*9)+(1*3)=120
120 % 10 = 0
So 14494-93-0 is a valid CAS Registry Number.
