64269-70-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64269-70-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,6 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 64269-70:
(7*6)+(6*4)+(5*2)+(4*6)+(3*9)+(2*7)+(1*0)=141
141 % 10 = 1
So 64269-70-1 is a valid CAS Registry Number.

Application of Azide-Tetrazole Tautomerism and Arylsulfanyl Group Dance in the Synthesis of Thiosubstituted Tetrazoloquinazolines

Jeminejs, Andris,Goli?kina, Svetlana M.,Novosjolova, Irina,Stepanovs, Dmitrijs,Bizdēna, ērika,Turks, Māris

, p. 1543 - 1556 (2021)

Nucleophilic aromatic substitution reaction between 4-aryl-thio-2-chloroquinazolines and NaN 3takes place with an unusual sulfanyl group dance and leads to the formation of 5-(arylthio)tetrazolo[1,5- c ]-quinazolines, which do not form the azide tautomer and do not undergo CuAAC reactions with alkynes. On the other hand, 5-azidotetrazolo[1,5- a ]quinazoline (formally described as 2,4-diazidoquinazoline) undergoes regioselective nucleophilic aromatic substitution with thiols at C5 and forms 5-(alkyl/arylthio)tetrazolo[1,5- a ]quinazolines, the structure of which has been proved by X-ray crystallography. The latter exist in tautomeric equilibrium with their 2-azidoquinazoline form, which provides possibility for copper-catalyzed azide-alkyne 1,3-dipolar cyclo-addition reaction, leading to the 4-alkyl/arylthio-2-(1 H -1,2,3-triazol-1-yl)quinazolines.
