107676-55-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 107676-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,6,7 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 107676-55:
(8*1)+(7*0)+(6*7)+(5*6)+(4*7)+(3*6)+(2*5)+(1*5)=141
141 % 10 = 1
So 107676-55-1 is a valid CAS Registry Number.

Pd/C Catalyzed Carbonylation of Azides in the Presence of Amines

Zhao, Jin,Li, Zongyang,Yan, Shuaihu,Xu, Shiyang,Wang, Ming-An,Fu, Bin,Zhang, Zhenhua

, p. 1736 - 1739 (2016/05/19)

A facile and efficient Pd/C-catalyzed carbonylation of both aliphatic and aromatic azides in the presence of amines is reported. Serving as the widely existed fragments in an array of biological pharmaceuticals, functionalized unsymmetrical ureas were str

Microwave assisted, ligand free, copper catalyzed reaction of aryl halides with phenyl urea

Gavade, Sandip N.,Balaskar, Ravi S.,Mane, Madhav S.,Pabrekar, Pramod N.,Shingare, Murlidhar S.,Mane, Dhananjay V.

experimental part, p. 292 - 295 (2012/01/05)

The ligand free coupling reaction of phenyl urea with different functionalized aryl halides in the presence of air stable Cu2O and t-BuOK as a base gives symmetrical and unsymmetrical diarylureas in relatively high yields. This method is milder than the palladium catalyzed arylation and avoids the use of toxic phosphine ligand.

Substituent effects on nitrosation of 1,3-diarylureas with nitrosyl chloride, dinitrogen trioxide, and dinitrogen tetroxide
