Check Digit Verification of cas no

The CAS Registry Mumber 180205-43-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,2,0 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 180205-43:
(8*1)+(7*8)+(6*0)+(5*2)+(4*0)+(3*5)+(2*4)+(1*3)=100
100 % 10 = 0
So 180205-43-0 is a valid CAS Registry Number.

Diastereoselective synthesis of hydantoin- and isoxazoline-substituted dispirocyclobutanoids

Park, Kyung-Ho,Kurth, Mark J.

, p. 3520 - 3524 (2007/10/03)

Synthetic strategies for constructing novel achiral cyclobutanoid isoxazolidinoimidazolidinedione heterocycles, with a generalized structure of II, have been developed via 1,3-dipolar cycloaddition and carbanilide cyclization transformations from methylenecyclobutane 13. The exo methylene cyclobutane system has made the realization of some diasteroselectivity possible, such that the H-bond (Boc-NH) directed product (i.e., 14) was obtained with 3:1 selectivity relative to the non-H-bond directed product (i.e., 15).
