Check Digit Verification of cas no

The CAS Registry Mumber 33681-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,8 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33681-53:
(7*3)+(6*3)+(5*6)+(4*8)+(3*1)+(2*5)+(1*3)=117
117 % 10 = 7
So 33681-53-7 is a valid CAS Registry Number.

N-alkoxyimidoyl bromides as a new and efficient coupling partner in Pd-catalyzed Stille reaction

Chang,Lee,Kim

, p. 1557 - 1558 (2001)

N-Alkoxyimidoyl bromides have been successfully employed as an efficient organic partner in the Pd-catalyzed Stille coupling reaction with various organotin compounds, and the corresponding O-alkyloximes were obtained in good to excellent yields.

Titanium tetraiodide promoted reductive opening of 2-(1-benzyloxyiminoethyl)aziridines, leading to aza-aldol reaction

Shimizu, Makoto,Nishiura, Shuji,Hachiya, Iwao

, p. 177 - 183 (2008/09/17)

Reductive ring-opening of 2-(1-benzyloxyiminoethyl)aziridines was regioselectively carried out with titanium tetraiodide to form the titanium aza-enolates, which in turn were subjected to addition reaction with aldehydes to give aza-aldol products in good yields with high diastereoselectivities.
