40060-76-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40060-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,6 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40060-76:
(7*4)+(6*0)+(5*0)+(4*6)+(3*0)+(2*7)+(1*6)=72
72 % 10 = 2
So 40060-76-2 is a valid CAS Registry Number.

N-Morpholinomethyl-5-lithiotetrazole: A Reagent for the One-Pot Synthesis of 5-(1-Hydroxyalkyl)tetrazoles

Alexakos, Panagiotis D.,Wardrop, Duncan J.

, p. 12430 - 12436 (2019)

An efficient, one-pot method for the preparation of 5-(1-hydroxyalkyl)tetrazoles is reported. N-Morpholinomethyl-5-lithiotetrazole, generated by the deprotonation of 4-(N-tetrazolylmethyl)morpholine with LiHMDS, undergoes addition to ketones and aldehydes (both aromatic and aliphatic) to form 5-(1-hydroxyalkyl)tetrazoles in a high yield, after acidic workup. The reported protocol displays a broad substrate scope and functional group tolerance, avoids the use of cyanide- or azide-based reagents, and provides access to sterically congested and unsaturated tetrazoles, which are difficult to access by other means.

Microwave Synthesis of 5-Substituted 1 H-Tetrazoles Catalyzed by Bismuth Chloride in Water

Coca, Adiel,Feinn, Liana,Dudley, Joshua

, p. 1023 - 1030 (2015/03/30)

(Chemical Equation Presented). Bismuth chloride was used to catalyze the [2 + 3] cycloaddition between sodium azide with aryl nitriles, aliphatic nitriles, and vinyl nitriles. A number of 5-substituted 1H-tetrazoles were synthesized in water or isopropano

Homologation of 1-(benzyloxymethyl)-1H-tetrazole via lithiation

Satoh, Yoshitaka,Moliterni, John

, p. 528 - 530 (2007/10/03)

Lithiation of 1-(Benzyloxymethyl)-1H-tetrazoIe, prepared by alkylation of 1H-tetrazole with benzyl chloromethyl ether, followed by treatement with a variety of electrophiles afforded its homologation products. Hydrogenation or acid hydrolysis gave the corresponding free tetrazoles.
