54199-54-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54199-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,9 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 54199-54:
(7*5)+(6*4)+(5*1)+(4*9)+(3*9)+(2*5)+(1*4)=141
141 % 10 = 1
So 54199-54-1 is a valid CAS Registry Number.

Base-promoted thioannulation of: O -alkynyl oxime ethers with sodium sulfide for the general synthesis of isothiocoumarins

Sun, Cai-Ling,Zhang, Xiao-Hong,Zhang, Xing-Guo,Zhang, Zhu-Zhu

, p. 10174 - 10180 (2021/12/10)

A general and efficient strategy for the one-pot synthesis of isothiocoumarin-1-ones has been developed via the base-promoted 6-endo-dig thioannulation of o-alkynyl oxime ethers using the cheap and readily available Na2S as the sulfur source. Mechanistic studies disclosed that the reaction proceeded through two C-S bond formations, N-O bond cleavage and the final hydrolysis of imines. This journal is
