209398-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209398-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,3,9 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 209398-38:
(8*2)+(7*0)+(6*9)+(5*3)+(4*9)+(3*8)+(2*3)+(1*8)=159
159 % 10 = 9
So 209398-38-9 is a valid CAS Registry Number.
