The CAS Registry Mumber 84609-10-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,0 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84609-10:
(7*8)+(6*4)+(5*6)+(4*0)+(3*9)+(2*1)+(1*0)=139
139 % 10 = 9
So 84609-10-9 is a valid CAS Registry Number.
