The CAS Registry Mumber 167173-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,1,7 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 167173-85:
(8*1)+(7*6)+(6*7)+(5*1)+(4*7)+(3*3)+(2*8)+(1*5)=155
155 % 10 = 5
So 167173-85-5 is a valid CAS Registry Number.

Enantioselective total synthesis of the antifungal dilactone, UK-2A: The determination of the relative and absolute configurations
Shimano, Masanao,Shibata, Tetsuo,Kamei, Noriyuki
, p. 4363 - 4366 (2007/10/03)
The synthesis of the antifungal dilactone, UK-2A, is described. In addition to providing a workable synthetic route to this potent antifungal antibiotic, this has allowed us to determine the assignment of the relative and absolute configurations in the nine-membered ring.
