69261-50-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69261-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,2,6 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69261-50:
(7*6)+(6*9)+(5*2)+(4*6)+(3*1)+(2*5)+(1*0)=143
143 % 10 = 3
So 69261-50-3 is a valid CAS Registry Number.

Oxidative photo-decarboxylation in the presence of mesoporous silicas

Itoh, Akichika,Kodama, Tomohiro,Masaki, Yukio,Inagaki, Shinji

, p. 1571 - 1575 (2006)

FSM-16, a mesoporous silica, was found to catalyze oxidative photo-decarboxylation of α-hydroxy carboxylic acid, phenyl acetic acid derivatives and N-acyl-protected α-amino acids to afford the corresponding carbonyl compounds. Furthermore, FSM-16 proved to be re-usable by re-calcination at 450°C after the reaction.

SALT OF ISOLATED COMPOUND CONTAINING AMIDE GROUP, METHOD FOR PRODUCING THE SAME, AND METHOD FOR SYNTHESIZING AMIDE COMPOUND USING THE SAME

Paragraph 0072; 0074; 0075, (2018/08/23)

PROBLEM TO BE SOLVED: To provide a salt of an isolated compound containing an amide group, a method for producing the same, and a method for synthesizing an amide compound using the same. SOLUTION: The present invention provides a salt of an isolated compound containing an amide group represented by formula (1) (M is an element belonging to group 1 in the periodic table; P is a first protective group of an amine represented by R1-O(C=O)-; Q is a second protective group of an amine represented by R2-(C=O)-; R1 and R2 independently represent a substituted/unsubstituted hydrocarbon group).

Short communication: Silica sulfuric acid: A versatile and reusable heterogeneous catalyst for the synthesis of N-ACYL carbamates and oxazolidinones under solvent-free conditions

Wu, Liqiang,Yang, Xiaojuan,Yan, Fulin

experimental part, p. 151 - 155 (2012/05/20)

Silica sulfuric acid catalyzes efficiently the reaction of carbamates and oxazolidinones with anhydrides under solvent-free conditions. All the reactions were done at room temperature and the N-acyl carbamates and oxazolidinones were obtained with high yi
