1234505-52-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1234505-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,5,0 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1234505-52:
(9*1)+(8*2)+(7*3)+(6*4)+(5*5)+(4*0)+(3*5)+(2*5)+(1*2)=122
122 % 10 = 2
So 1234505-52-2 is a valid CAS Registry Number.

Rhodium-catalyzed synthesis of γ-butyrolactams and pyrrolidines via cycloisomerization of N-tethered 1,6-enynes

Wang, Jianping,Xie, Xiaomin,Ma, Fangfang,Peng, Zhiyong,Zhang, Lei,Zhang, Zhaoguo

, p. 4212 - 4217 (2010)

A rhodium-catalyzed cycloisomerization reaction of N-tethered 1,6-enynes with an intramolecular halogen shift has been developed, providing a useful process for the synthesis of stereo defined γ-butyrolactam and pyrrolidine derivatives in good to excellent yields. Effects of both electronic feature and steric structure of the substrates on the outcome of the reaction were investigated.
