69047-40-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69047-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,4 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69047-40:
(7*6)+(6*9)+(5*0)+(4*4)+(3*7)+(2*4)+(1*0)=141
141 % 10 = 1
So 69047-40-1 is a valid CAS Registry Number.

A straightforward synthesis of N-monosubstituted α-keto amides via aerobic benzylic oxidation of amides

Shao, Jun,Huang, Xiaomei,Wang, Siyuan,Liu, Bingxin,Xu, Bin

supporting information; experimental part, p. 573 - 579 (2012/01/13)

An efficient sodium bicarbonate promoted aerobic oxidation reaction to prepare N-monosubstituted α-keto amides in the presence of n-tetrabutylammonium hydrogensulfate (TBAHS) was described. This reaction provides a very simple and convenient synthetic route to N-monosubstituted α-keto amides from easily available aryl- or heteroarylacetamides in good to high yields without using toxic reagents and harsh conditions.

Zeolite-HY : A selective and efficient catalyst for the synthesis of amides under microwave irradiations

Gadhwal, Sunil,Dutta, Manu Prakash,Boruah, Anima,Prajapati, Dipak,Sandhu, Jagir S.

, p. 725 - 727 (2007/10/03)

An efficient and selective method for the conversion of various acids into their corresponding amides in the presence of zeolite under microwave irradiation is described. The reaction proceeds efficiently at ambient pressure in high yields.
