Check Digit Verification of cas no

The CAS Registry Mumber 1345403-82-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,4,0 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1345403-82:
(9*1)+(8*3)+(7*4)+(6*5)+(5*4)+(4*0)+(3*3)+(2*8)+(1*2)=138
138 % 10 = 8
So 1345403-82-8 is a valid CAS Registry Number.

Copper porphyrin-catalyzed cross dehydrogenative coupling of alkanes with carboxylic acids: Esterification and decarboxylation dual pathway

Chen, Xiao-Yan,Yang, Shuang,Ren, Bao-Ping,Shi, Lei,Lin, Dong-Zi,Zhang, Hao,Liu, Hai-Yang

, (2021/08/13)

A dual-functional copper porphyrin-catalyzed cross dehydrogenative coupling (CDC) of carboxylic acids with alkanes was reported firstly. The reaction gives allylic esters or alkylalkenes depending on the carboxylic acid substrates. Copper porphyrin catalyzed CDC method has the superiority of short reaction time, good functional group tolerance, base and solvent free, producing target products in an atom-economic manner.

Copper porphyrin as efficient catalysts for esterification of allyl sp3 C–H bond with carboxylic acid

Xiong, Ming-Feng,Ali, Atif,Akram, Waseem,Zhang, Hao,Si, Li-Ping,Liu, Hai-Yang

, p. 93 - 97 (2019/04/08)

We described that copper 5,10,15,20-tetrakis (ethoxycarbonyl)porphyrin (TECP) catalyzed oxidative cross dehydrogenative coupling of allyl sp3 C–H bond with acid for the synthesis of allyl esters in a homogeneous system. This reaction proceeded

Bu4NI-catalyzed construction of tert-butyl peresters from alcohols

Zhang, Hui,Dong, Dao-Qing,Hao, Shuang-Hong,Wang, Zu-Li

, p. 8465 - 8468 (2016/02/09)

A new method for the synthesis of tert-butyl peresters directly from available alcohols catalyzed by Bu4NI at room temperature in an aqueous system was developed. Additionally, allylic esters could also be obtained by combing this method and Kharasch-Sosnovsky reaction via a two-step one-pot procedure.
