Check Digit Verification of cas no

The CAS Registry Mumber 28991-09-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,9,9 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28991-09:
(7*2)+(6*8)+(5*9)+(4*9)+(3*1)+(2*0)+(1*9)=155
155 % 10 = 5
So 28991-09-5 is a valid CAS Registry Number.

Lewis acid-catalyzed annulative partial dimerization of 3-aryloxyacrylates to 4-arylchroman-2-ones: Synthesis of analogues of tolterodine, RORγ inhibitors and a GPR40 agonist

Kunkalkar, Rupesh A.,Fernandes, Rodney A.

, p. 2313 - 2316 (2019)

A beguiling annulative partial dimerization of 3-aryloxyacrylates to 4-arylchroman-2-ones catalyzed by Lewis acid (BF3·OEt2) has been developed. The reaction involves two molecules of 3-aryloxyacrylate, resulting in the loss of one propiolate molecule to furnish 4-arylchroman-2-one, an important structural motif found in many natural products. This methodology has been elaborated to synthesize analogues of tolterodine, RORγ inhibitors and a GPR40 agonist.

Palladium-catalyzed oxidative cyclization of 3-phenoxyacrylates: An approach to construct substituted benzofurans from phenols

Li, Chengliang,Zhang, Yicheng,Li, Pinhua,Wang, Lei

body text, p. 4692 - 4696 (2011/07/08)

In this paper, a novel and applicable synthesis of benzofurans from commercially available phenols and propiolate through the direct oxidative cyclization has been developed. In the presence of Pd(OAc)2/PPh 3 and CF3COsub
