209262-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209262-83-9 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 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 209262-83:
(8*2)+(7*0)+(6*9)+(5*2)+(4*6)+(3*2)+(2*8)+(1*3)=129
129 % 10 = 9
So 209262-83-9 is a valid CAS Registry Number.
