72511-60-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72511-60-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,5,1 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72511-60:
(7*7)+(6*2)+(5*5)+(4*1)+(3*1)+(2*6)+(1*0)=105
105 % 10 = 5
So 72511-60-5 is a valid CAS Registry Number.

Vitamin B1-catalyzed aerobic oxidative esterification of aromatic aldehydes with alcohols

Chu, Xue-Qiang,Ge, Danhua,Luo, Xin-Long,Xu, Pei,Yu, Zi-Lun

supporting information, p. 30937 - 30942 (2021/11/19)

A straightforward aerobic oxidative esterification of aryl aldehydes with alcohols has been developed for the synthesis of substituted esters by employing vitamin B1 as a cost-effective, metal-free, and eco-friendly NHC catalyst. Air is used as a green terminal oxidant. The reaction is a useful addition to the existing NHC-catalytic oxidative esterification.

Water-soluble alkyne amide condensing agent as well as preparation method and application thereof

-

Paragraph 0201-0206, (2021/02/10)

The invention discloses a water-soluble alkyne amide condensing agent and an application method of the water-soluble alkyne amide condensing agent in synthesis of amide, polypeptide, ester and thioester compounds. The alkyne amide condensing agent has good performance and can efficiently and conveniently promote formation of amide bonds and ester bonds, alpha-chiral centers of carboxylic acid is free of racemization in the reaction process, carboxylic acid activation and a subsequent amidation reaction can be performed spontaneously, and extra additives and catalysts are not needed. After amidation and esterification reactions are finished, reaction by-products and the excessive alkyne amide condensing agent can be converted into substances capable of being dissolved in water through treatment by a weakly-acidic aqueous solution, and then high-purity products can be obtained through extraction and/or recrystallization. The whole process is simple to operate, has the characteristics ofconvenience in purification, wide application range, economic performance and environmental protection, conforms to the direction of green chemistry in modernization, and has good application prospects.

Aromatic carboxylic acid trifluoro ethyl ester compound and its preparation method (by machine translation)
