The CAS Registry Mumber 280136-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,0,1,3 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 280136-80:
(8*2)+(7*8)+(6*0)+(5*1)+(4*3)+(3*6)+(2*8)+(1*0)=123
123 % 10 = 3
So 280136-80-3 is a valid CAS Registry Number.
