173045-49-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 173045-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,0,4 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 173045-49:
(8*1)+(7*7)+(6*3)+(5*0)+(4*4)+(3*5)+(2*4)+(1*9)=123
123 % 10 = 3
So 173045-49-3 is a valid CAS Registry Number.

A convenient way for alkylation of amines using xanthate esters

Sukrutha, Kodipura P.,Swaroop, Toreshettahally R.,Preetham, Ramesh,Lokanath, Neratur K.,Rangappa, Kanchugarakoppal S.,Sadashiva, Maralinganadoddi P.

, p. 2316 - 2323 (2021/06/14)

N-alkylation of amines by the reaction with xanthate esters in the presence of acetic acid catalyst in ethanol is reported. Short reaction time, high yield, general applicability and environmentally benign nature are the noteworthy features of our protocol. The probable mechanism for the formation N-alkylation of amines is proposed.

Convenient and stereoselective synthesis of symmetrical (E)-stilbenes via homocoupling of 1,3-dibenzylbenzotriazolium bromides

Xiao, Xiaohui,Lin, Daqin,Tong, Shuitian,Luo, Hong,He, Yinfeng,Mo, Hailan

supporting information; experimental part, p. 1731 - 1734 (2011/09/16)

Using NaH as the base and DMSO as the solvent, a series of symmetric (E)-stilbenes were prepared in good yields via the -homocoupling of 1,3-dibenzylbenzotriazolium bromides at room temperature. Georg Thieme Verlag Stuttgart · New York.

Nucleophilic substitution of benzotriazolylalkyl chlorides with Grignard reagents: A direct route to benzotriazoloalkyl(hetero)aromatic compounds

Katritzky, Alan R.,Abdel-Fattah, Ashraf A. A.,Tymoshenko, Dmytro O.,Belyakov, Sergei A.

, p. 1437 - 1440 (2007/10/03)

Benzotriazolylalkyl chlorides 5 react with (hetero)aromatic Grignard reagents generated from the corresponding halogen derivatives to afford benzotriazoloalkyl(hetero)aromatic compounds 8a-k and 10a-c in good yields.
