77627-63-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77627-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,2 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77627-63:
(7*7)+(6*7)+(5*6)+(4*2)+(3*7)+(2*6)+(1*3)=165
165 % 10 = 5
So 77627-63-5 is a valid CAS Registry Number.

One pot synthesis using supported reagents system KSCN/SiO 2-RNH3OAc/Al2O3: Synthesis of 2-aminothiazoles and N-allylthioureas

Aoyama, Tadashi,Murata, Sumiko,Arai, Izumi,Araki, Natsumi,Takido, Toshio,Suzuki, Yoshitada,Kodomari, Mitsuo

, p. 3201 - 3213 (2007/10/03)

A simple and efficient method has been developed for the synthesis of 2-aminothiazoles and N-allylthioureas from commercially available materials in one pot by using a supported reagents system, KSCN/SiO2-RNH 3OAc/Al2O3, in which α-halo ketone reacts first KSCN/SiO2 and the product, α-thiocyanatoketone, reacts with RNH3OAc/Al2O3 to give the final product, 2-aminothiazoles, in good yield and allyl bromide reacts with KSCN/SiO 2 and the product, allyl isothiocyanate, reacts with RNH 3OAc/Al2O3 to give N-allylthiourea.

Synthesis of N-(2-Substituted-ethyl)-N'-arylpiperazines and Their Quaternary Salts as Potential Antihookworm Agents

Rastogi, Rashmi,Sharma, Satyavan,Iyer, R. N.

, p. 1003 - 1005 (2007/10/02)

A series of N-(2-substituted-ethyl)-N'-arylpiperazines (4-15) and their quaternary salts (17-21) have been prepared and tested for their antihookworm activity against Nippostrongylus brasiliensis in rats and Nematospiroides dubius in mice.Of the compounds
