Check Digit Verification of cas no

The CAS Registry Mumber 89549-37-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,4 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89549-37:
(7*8)+(6*9)+(5*5)+(4*4)+(3*9)+(2*3)+(1*7)=191
191 % 10 = 1
So 89549-37-1 is a valid CAS Registry Number.

Method for catalytically oxidizing amine to be synthesized into amide through dipyridyl-type manganese catalyst

-

Paragraph 0017-0027; 0073-0075, (2019/06/30)

The invention discloses a methodfor catalytically oxidizing amine to be synthesized into amide througha dipyridyl-type manganese catalyst. According to the method, a dipyridyl manganese complex formedafter coordination of a dipyridyl-type complex and cheap metal manganese serves as the catalyst, clean and environment-friendly hydrogen peroxide serves as an oxidizing agent, oxidation of N ortho-position sp3 C-H bonds catalyzed by the cheap metal manganese is achieved, and the amine is directly oxidized to obtain the amide. Compared with existing methods, the method has the advantages that theadopted catalyst is low in price, the preparing method is simple, raw materials are easy to obtain, the use level of the catalyst is low, the substrate range is wide, the reaction condition is mild, the operation is simple and environmentally friendly, the reaction time is short, the yield is high, the selectivity is high, and the industrialization cost is low.

Transition-Metal- and Halogen-Free Oxidation of Benzylic sp 3 C-H Bonds to Carbonyl Groups Using Potassium Persulfate

Hu, Yixin,Zhou, Lihong,Lu, Wenjun

, p. 4007 - 4016 (2017/08/29)

Aryl carbonyl compounds including acetophenones, benzophenones, imides, and benzoic acids are prepared from benzyl substrates using potassium persulfate as oxidant with catalytic pyridine in acetonitrile under mild conditions. Neither transition metals nor halogens are involved in the reactions.

Synthesis of 1,3,5-trisubstituted-1,2,4-triazoles by microwave-assisted N-acylation of amide derivatives and the consecutive reaction with hydrazine hydrochlorides

Lee, Jongbok,Hong, Myengchan,Jung, Yoonchul,Cho, Eun Jin,Rhee, Hakjune

experimental part, p. 2045 - 2051 (2012/04/10)

Facile and efficient procedures for the N-acylation reaction of amide derivatives with various acid anhydrides and the cyclization reaction of N-acylated amide derivatives with various hydrazine hydrochlorides were described. The reactions were carried out under microwave irradiation to give products in good yields in a few minutes. The synthesis of 1,3,5-trisubstituted- 1,2,4-triazoles from benzamides can also be accomplished in a simple one-pot sequential reaction.
