The CAS Registry Mumber 123186-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,1,8 and 6 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 123186-89: (8*1)+(7*2)+(6*3)+(5*1)+(4*8)+(3*6)+(2*8)+(1*9)=120 120 % 10 = 0 So 123186-89-0 is a valid CAS Registry Number.
