177697-55-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 177697-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,6,9 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 177697-55:
(8*1)+(7*7)+(6*7)+(5*6)+(4*9)+(3*7)+(2*5)+(1*5)=201
201 % 10 = 1
So 177697-55-1 is a valid CAS Registry Number.

Reaction of tributyltin hydride with α,β-unsaturated N-acyloxazolidinones

Wu, Ming-Jung,Fu, Chia-Lin,Duh, Tsai-Hui,Yeh, Jiann-Yih

, p. 462 - 464 (1996)

The treatment of tributyltin hydride with α-substituted propenoyl oxazolidinones in the presence of a catalytic amount of AIBN gave the tributyltin radical addition adduct when the substituent is an alkyl group. However, when the substituent is an aryl gr

Resolution of pentafluorophenyl 2-phenylpropanoate using combinations of quasi-enantiomeric oxazolidin-2-ones

Shaye, Najla Al,Benoit, David M.,Chavda, Sameer,Coulbeck, Elliot,Dingjan, Marco,Eames, Jason,Yohannes, Yonas

, p. 413 - 438 (2011/06/17)

The kinetic, mutual and parallel resolution of a series of structurally related active esters derived from 2-phenylpropanoic acid using a combination of quasi-enantiomeric oxazolidin-2-ones is discussed.

Parallel kinetic resolution of racemic oxazolidinones using quasi-enantiomeric active esters

Boyd, Ewan,Coulbeck, Elliot,Coumbarides, Gregory S.,Chavda, Sameer,Dingjan, Marco,Eames, Jason,Flinn, Anthony,Motevalli, Majid,Northen, Julian,Yohannes, Yonas

, p. 2515 - 2530 (2008/03/15)

Racemic Evans' oxazolidinones were efficiently resolved using a combination of quasi-enantiomeric profens. The levels of stereocontrol were high, leading to products with predictable configurations.
