5180-31-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5180-31-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,8 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5180-31:
(6*5)+(5*1)+(4*8)+(3*0)+(2*3)+(1*1)=74
74 % 10 = 4
So 5180-31-4 is a valid CAS Registry Number.

Direct and facile synthesis of acyl azides from carboxylic acids using the trichloroisocyanuric acid-triphenylphosphine system

Akhlaghinia, Batool,Rouhi-Saadabad, Hamed

, p. 181 - 185 (2013/05/09)

A mild, efficient, and practical method for the one-step synthesis of acyl azides from carboxylic acids using a safe and inexpensive mixed reagent, trichloroisocyanuric acid-triphenylphosphine, is described.

Direct synthesis of acyl azides from carboxylic acids using 2-azido-l,3-dimethylimidazolinium chloride

Kitamura, Mitsuru,Tashiro, Norifumi,Takamoto, Yusuke,Okauchi, Tatsuo

scheme or table, p. 731 - 733 (2011/01/08)

Acyl azides were directly synthesized from carboxylic acids by the treatment with 2-azido-l,3-dimethylimidazolinium chloride (ADMC, 1) and amine. This procedure resulted in acyl azides in good yields and was applied to the amidation of amino acid derivatives without racemization of the products.

A new facile and rapid synthesis of acyl azides under solvent-free conditions

Mallakpour,Hajipour,Vahabi

, p. 1234 - 1235 (2007/10/03)

A rapid and simple method for the preparation of acyl azides is described. The reaction is carried out under solvent-free conditions from the reaction of acid chlorides with sodium azide supported on silica gel.

One-flask conversion of carboxylic acids into carbamoyl azides

Froyen

, p. 4549 - 4561 (2007/10/03)

Carbamoyl azides can be generated in high yields from the corresponding carboxylic acid and triphenylphosphine by adding NCS, followed by sodium azide and triethylamine hydrochloride.
