227202-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 227202-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,2,0 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 227202-21:
(8*2)+(7*2)+(6*7)+(5*2)+(4*0)+(3*2)+(2*2)+(1*1)=93
93 % 10 = 3
So 227202-21-3 is a valid CAS Registry Number.

A mild and facile method for the synthesis of 3-cyano-chromones from oximes derived from 3-formylchromones using dimethylformamide-thionylchloride complex

Jagath Reddy,Latha,Srinivasa Rao

, p. 279 - 282 (2004)

A mild and facile method for the synthesis of 3-cyanochromones (4) from oximes (2) derived from 3-formylchromones using Dimethylformamide- thionylchloride complex (1) is herein reported.

Metal-free access to 3-allyl-2-alkoxychromanonesviaphosphine-catalyzed alkoxy allylation of chromones with MBH carbonates and alcohols

Meng, Ling,Chang, Xiaoyong,Lin, Zhenyang,Wang, Jun (Joelle)

supporting information, p. 2663 - 2667 (2021/04/07)

A metal-free access to 3-allyl-2-alkoxychromanones by PPh3-catalyzed alkoxy allylation of chromones with MBH carbonates and alcohols is described. This reaction is performed under mild conditions and it shows good functional group tolerance, providing a series of functionalized chromanones in moderate to high yields with excellent diastereoselectivities. Deuterium-labeling experiments to probe a possible mechanism and scale-up reaction were also conducted.
