209518-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209518-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,5,1 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 209518-76:
(8*2)+(7*0)+(6*9)+(5*5)+(4*1)+(3*8)+(2*7)+(1*6)=143
143 % 10 = 3
So 209518-76-3 is a valid CAS Registry Number.
