209403-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209403-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,4,0 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 209403-38:
(8*2)+(7*0)+(6*9)+(5*4)+(4*0)+(3*3)+(2*3)+(1*8)=113
113 % 10 = 3
So 209403-38-3 is a valid CAS Registry Number.
