151231-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 151231-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,2,3 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 151231-67:
(8*1)+(7*5)+(6*1)+(5*2)+(4*3)+(3*1)+(2*6)+(1*7)=93
93 % 10 = 3
So 151231-67-3 is a valid CAS Registry Number.

A simple one-pot method for the preparation of allyl azides from allyl alcohols using triphosgene: Synthesis of N1-cinnamyl azetidin-2-ones

Jayanthi,Gumaste,Deshmukh

, p. 979 - 982 (2007/10/03)

A simple and efficient one-pot method for the preparation of allyl azides from allyl alcohols using triphosgene and sodium azide is described. An application of cinnamyl azide for the synthesis of various N1 -cinnamyl azetidin-2-ones is also described.

An efficient one-pot conversion of alkyl bromides into imines via the Staudinger reaction

Vanek, Petr,Klan, Petr

, p. 1503 - 1507 (2007/10/03)

A new one-pot procedure for transforming primary alkyl bromides into the corresponding imines via the Staudinger reaction has been developed. Acetonitrile was found to be an excellent solvent for azidation as well as the reaction of organic azide with triphenylphosphine and a carbonyl compound.

Iminophosphorane-mediated one-pot conversion of allyl azides into α-allylated nitriles by a consecutive staudinger reaction/aza-wittig reaction/3-aza-claisen rearrangement process

Molina,Alajarin,Lopez-Leonardo

, p. 4041 - 4044 (2007/10/02)

One-pot conversion of allyl azides 1 into nitriles 3 under mild and neutral conditions is reported. The method involves sequential treatment of 1 with triphenylphosphine and the corresponding ketene to give 3.
