The CAS Registry Mumber 120285-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,8 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120285-20:
(8*1)+(7*2)+(6*0)+(5*2)+(4*8)+(3*5)+(2*2)+(1*0)=83
83 % 10 = 3
So 120285-20-3 is a valid CAS Registry Number.
