1233689-41-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1233689-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,6,8 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1233689-41:
(9*1)+(8*2)+(7*3)+(6*3)+(5*6)+(4*8)+(3*9)+(2*4)+(1*1)=162
162 % 10 = 2
So 1233689-41-2 is a valid CAS Registry Number.

Enantioselective synthesis of 3,4-chromanediones via asymmetric rearrangement of 3-allyloxyflavones

Marie, Jean-Charles,Xiong, Yuan,Min, Geanna K.,Yeager, Adam R.,Taniguchi, Tohru,Berova, Nina,Schaus, Scott E.,Porco, John A.

, p. 4584 - 4590 (2010)

(Figure presented) Asymmetric scandium(III)-catalyzed rearrangement of 3-allyloxyflavones was utilized to prepare chiral, nonracemic 3,4-chromanediones in high yields and enantioselectivities. These synthetic intermediates have been further elaborated to novel heterocyclic frameworks including angular pyrazines and dihydropyrazines. The absolute configuration of rearrangement products was initially determined by a nonempirical analysis of circular dichroism (CD) using time-dependent density functional theory (TDDFT) calculations and verified by X-ray crystallography of a hydrazone derivative. Initial studies of the mechanism support an intramolecular rearrangement pathway that may proceed through a benzopyrylium intermediate.
