Check Digit Verification of cas no

The CAS Registry Mumber 15074-17-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,7 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 15074-17:
(7*1)+(6*5)+(5*0)+(4*7)+(3*4)+(2*1)+(1*7)=86
86 % 10 = 6
So 15074-17-6 is a valid CAS Registry Number.

Preparation of 4-Hydroxy-3-Substituted, 2H-1-Benzopyran-2-ones and 2H-1-Benzothiopyran-2-ones from Carboxylic Esters and Methyl Salicylates or Methyl Thiosalicylate

Davis, Sharon E.,Church, A. Cameron,Tummons, Rebecca C.,Beam, Charles F.

, p. 1159 - 1162 (1997)

C(α)-Carboxylic acid esters were treated with excess lithium diisopropylamide, condensed with methyl salicylates or methyl thiosalicylate, followed by acid cyclization to either 4-hydroxy-3-substituted, 2H-1-benzopyran-2-ones (coumarins), or 2H-1-benzothiopyran-2-ones (thiocoumarins).

Rh-Catalyzed domino synthesis of 4-hydroxy-3-methylcoumarins via branch-selective hydroacylation

Rao, Maddali L.N.,Ramakrishna, Boddu S.,Nand, Sachchida

supporting information, p. 9275 - 9279 (2019/11/13)

A Rh-catalyzed domino synthesis of 4-hydroxy-3-methylcoumarins via branch-selective hydroacylation of acrylates and acrylamides using salicylaldehydes is described. This protocol under phosphine-free Rh-catalyzed conditions provided 4-hydroxy-3-methylcoum

A Baker-Venkataraman retro-Claisen cascade delivers a novel alkyl migration process for the synthesis of amides

Ameen, Dana,Snape, Timothy J.

, p. 1816 - 1819 (2015/03/30)

A simple extension of the carbamoyl Baker-Venkataraman rearrangement has been developed. If residual water in the reaction is not strictly excluded a Baker-Venkataraman retro-Claisen cascade takes place, giving amide products, in which an alkyl group apparently migrates between two functionalities of the substrate.
