Calculate Digit Verification of CAS Registry Number 91622-87:
(7*9)+(6*1)+(5*6)+(4*2)+(3*2)+(2*8)+(1*7)=136
136 % 10 = 6
So 91622-87-6 is a valid CAS Registry Number.

STEREOSELECTIVITIES OF BENZONITRILE OXIDE CYCLOADDITIONS TO CIS DISUBSTITUTED CYCLOPENTENES AND DIHYDROFURANS

Caramella, P.,Albini, Marinone F.,Vitali, D.,Rondan, Nelson G.,Wu, Yun-Dong,et al.

, p. 1875 - 1878 (2007/10/02)

Benzonitrile oxide cycloadds preferentially anti to the substituents of cis-3,5-di-X-cyclopentenes, where X= OMe, OAc, OCOPh, Br, Cl, and OH.Higher stereoselectivities are found for cis-2,5-di-X-2,5-dihydrofurans.The origins of these selectivities, and contrasts with acyclic and cyclobutene analogs, are described.
