133031-53-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133031-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,3 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133031-53:
(8*1)+(7*3)+(6*3)+(5*0)+(4*3)+(3*1)+(2*5)+(1*3)=75
75 % 10 = 5
So 133031-53-5 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

A new and concise synthesis of 3-aryl- and 3-alkyl-1H-2-benzothiopyran-1-ones (Thioisocoumarins)

Couture,Cornet,Grandclaudon

, p. 1133 - 1134 (2007/10/02)

3-Aryl-and 3-alkyl-1H-2-benzothiopyran-1-ones are readily accessible by reaction of the lithiated N,N-diethyl-o-toluamide (N,N-diethyl-2-methylbenzenecarboxamide) with appropriate aromatic, heteroaromatic and aliphatic thioesters.
