The CAS Registry Mumber 209805-96-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,8,0 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 209805-96:
(8*2)+(7*0)+(6*9)+(5*8)+(4*0)+(3*5)+(2*9)+(1*6)=149
149 % 10 = 9
So 209805-96-9 is a valid CAS Registry Number.
