82126-34-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82126-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,2 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82126-34:
(7*8)+(6*2)+(5*1)+(4*2)+(3*6)+(2*3)+(1*4)=109
109 % 10 = 9
So 82126-34-9 is a valid CAS Registry Number.

Imidazole-catalyzed monoacylation of symmetrical diamines

Verma, Sanjeev K.,Acharya,Kaushik

supporting information; experimental part, p. 4232 - 4235 (2010/11/04)

Figure Presented. An imidazole-catalyzed protocol for monoacylation of symmetrical diamines has been developed. The protocol gave selective monoacylation of aliphatic (cyclic and acyclic) primary and secondary diamines. In the reaction, imidazole acts as both catalyst and a leaving group. Different monoacylated piperazines and other diamines were synthesized at room temperature in an ethanol/water solvent system.

SYNTHESIS WITH SILICON DERIVATIVES: NON SYMMETRICAL DERIVATIZATION OF SYMMETRICAL DIAMINES

Schwartz, Eduard,Shanzer, Abraham

, p. 979 - 982 (2007/10/02)

The conversion of symmetrical diamines to monoamides via the use of cyclic siliconnitrogen compounds as intermediates is described.
