The CAS Registry Mumber 109875-69-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,7 and 5 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 109875-69: (8*1)+(7*0)+(6*9)+(5*8)+(4*7)+(3*5)+(2*6)+(1*9)=166 166 % 10 = 6 So 109875-69-6 is a valid CAS Registry Number.
