209266-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209266-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,2,6 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 209266-23:
(8*2)+(7*0)+(6*9)+(5*2)+(4*6)+(3*6)+(2*2)+(1*3)=129
129 % 10 = 9
So 209266-23-9 is a valid CAS Registry Number.
