14903-93-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14903-93-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,0 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 14903-93:
(7*1)+(6*4)+(5*9)+(4*0)+(3*3)+(2*9)+(1*3)=106
106 % 10 = 6
So 14903-93-6 is a valid CAS Registry Number.
