209054-80-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209054-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,0,5 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 209054-80:
(8*2)+(7*0)+(6*9)+(5*0)+(4*5)+(3*4)+(2*8)+(1*0)=118
118 % 10 = 8
So 209054-80-8 is a valid CAS Registry Number.
