93189-11-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93189-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,1,8 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93189-11:
(7*9)+(6*3)+(5*1)+(4*8)+(3*9)+(2*1)+(1*1)=148
148 % 10 = 8
So 93189-11-8 is a valid CAS Registry Number.

Development of Gold-catalyzed [4+1] and [2+2+1]/[4+2] Annulations between Propiolate Derivatives and Isoxazoles

Sahani, Rajkumar Lalji,Liu, Rai-Shung

, p. 1026 - 1030 (2017/01/18)

Two new gold-catalyzed annulations of isoxazoles with propiolates have been developed. Most isoxazoles follow an initial O attack on the alkyne to afford a [4+1] annulation product. This process results in a remarkable alkyne cleavage of initial propiolates. Unsubstituted isoxazoles proceed through an N attack step to yield formal [2+2+1]/[4+2] annulation products. These two annulation products arise initially from two seven-membered heterocyclic intermediates, which then lead to products.

Synthesis of 2-benzoylpyrrole derivatives via C-H functionalization adjacent to nitrogen of pyrrole

Guo, Zhiqiang,Wei, Xuehong,Hua, Yupeng,Chao, Jianbin,Liu, Diansheng

, p. 3919 - 3922 (2015/06/08)

A direct transition-metal-free synthesis of 2-benzoylpyrrole derivatives from free (N-H) pyrroles and benzaldehyde has been developed. The benzoylation reaction at the 2 or 5-position of pyrrole proceeded well under the alkali metalation system and with 2
