The CAS Registry Mumber 23844-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,8,4 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 23844-89:
(7*2)+(6*3)+(5*8)+(4*4)+(3*4)+(2*8)+(1*9)=125
125 % 10 = 5
So 23844-89-5 is a valid CAS Registry Number.
