The CAS Registry Mumber 109023-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,2 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109023-26:
(8*1)+(7*0)+(6*9)+(5*0)+(4*2)+(3*3)+(2*2)+(1*6)=89
89 % 10 = 9
So 109023-26-9 is a valid CAS Registry Number.
