Check Digit Verification of cas no

The CAS Registry Mumber 1558046-43-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,8,0,4 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1558046-43:
(9*1)+(8*5)+(7*5)+(6*8)+(5*0)+(4*4)+(3*6)+(2*4)+(1*3)=177
177 % 10 = 7
So 1558046-43-7 is a valid CAS Registry Number.

Biomimetic synthesis of (-)-chaetominine epimers via copper-catalyzed radical cyclization

Deng, Xu,Liang, Kangjiang,Tong, Xiaogang,Ding, Ming,Li, Dashan,Xia, Chengfeng

, p. 3699 - 3704 (2015)

Synthetic endeavors toward (-)-chaetominine via copper-catalyzed radical cyclization are reported. Both of the pyrido[2,3,b]-indole ring (C ring) and imidazolidinone (D ring) are efficiently constructed in one-pot manner. It's unveiled that the newly form

Complexity generation by chemical synthesis: A five-step synthesis of (-)-chaetominine from l-tryptophan and its biosynthetic implications

Xu, Chu-Pei,Luo, Shi-Peng,Wang, Ai-E,Huang, Pei-Qiang

supporting information, p. 2859 - 2863 (2014/05/06)

We demonstrated, for the first time, that on the basis of chemistry principles, the hexacyclic peptidyl alkaloid (-)-chaetominine (1) can be synthesized in a straightforward manner from l-Trp. The approach features the efficient generation of molecular complexity via a tandem C3/C14 syn-selective epoxidation (dr = 3:2)-annulative ring-opening reaction and a regioselective epimerization at C14. The successful production of (-)-chaetominine (1) from l-Trp could be helpful for revealing how the configuration of l-tryptophan becomes inverted in the biosynthetic pathway of (-)-chaetominine (1). This journal is the Partner Organisations 2014.
