108840-87-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 108840-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,8,4 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 108840-87:
(8*1)+(7*0)+(6*8)+(5*8)+(4*4)+(3*0)+(2*8)+(1*7)=135
135 % 10 = 5
So 108840-87-5 is a valid CAS Registry Number.

Designing a new basic ionic liquid [DHIM][OH] as a task specific bifunctional catalyst for facile microwave assisted metal free synthesis of 5-amino-1,2,3-triazoles

Dutta, Bidyutjyoti,Garg, Anirban,Kulshrestha, Akshay,Kumar, Arvind,Phukan, Parmita,Sarma, Diganta

supporting information, p. 12792 - 12797 (2021/08/04)

A green protocol for the synthesis of a series of 5-amino-1,2,3-triazoles from benzyl cyanide and phenyl azide derivatives catalyzed by the novel bifunctional ionic liquid [DHIM][OH] under microwave irradiation has been developed. The bifunctional ionic l

Azide-acetonitrile "click" reaction triggered by Cs2CO3: The atom-economic, high-yielding synthesis of 5-amino-1,2,3-triazoles

Krishna, Patoju M.,Ramachary, Dhevalapally B.,Peesapati, Sruthi

, p. 62062 - 62066 (2015/08/03)

Medicinally important 5-amino-1,2,3-triazoles were synthesized using a novel Cs2CO3-catalyzed azide-acetonitrile[3 + 2]-cycloaddition. Aryl azides and aryl acetonitriles were employed in this transformation resulting in excellent yie
