The CAS Registry Mumber 1234880-84-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,8,8 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1234880-84:
(9*1)+(8*2)+(7*3)+(6*4)+(5*8)+(4*8)+(3*0)+(2*8)+(1*4)=162
162 % 10 = 2
So 1234880-84-2 is a valid CAS Registry Number.
