162222-05-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 162222-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,2,2 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 162222-05:
(8*1)+(7*6)+(6*2)+(5*2)+(4*2)+(3*2)+(2*0)+(1*5)=91
91 % 10 = 1
So 162222-05-1 is a valid CAS Registry Number.

Asymmetric Synthesis of α-Chloro-α-halo Ketones by Decarboxylative Chlorination of α-Halo-β-ketocarboxylic Acids

Iwasa, Seiji,Kitahara, Kazumasa,Mizutani, Haruna,Shibatomi, Kazutaka

, p. 4385 - 4392 (2019)

Chiral α-chloro-α-fluoro ketones were synthesized by enantio-selective decarboxylative chlorination of α-chloro-β-ketocarboxylic acids in the presence of a chiral amine catalyst. The reaction yielded the corresponding α-chloro-α-fluoro ketones with modera

Catalytic enantioselective carbon insertion into the β-vinyl C-H bond of cyclic enones

Lee, Sung Il,Hwang, Geum-Sook,Ryu, Do Hyun

supporting information, p. 7126 - 7129 (2013/07/05)

Chiral oxazaborolidinium ion-catalyzed Csp2-H functionalization of enones using diazoacetate has been developed. Various β-substituted cyclic enones were synthesized in high yield (up to 99%) with high to excellent enantioselectivity (up to 99%
