855422-02-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 855422-02-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,4,2 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 855422-02:
(8*8)+(7*5)+(6*5)+(5*4)+(4*2)+(3*2)+(2*0)+(1*2)=165
165 % 10 = 5
So 855422-02-5 is a valid CAS Registry Number.

Microwave-Assisted 1,3-Dioxa-[3,3]-Sigmatropic Rearrangement of Substituted Allylic Carbamates: Application to the Synthesis of Novel 1,3-Oxazine-2,4-dione Derivatives

Bou Zeid, Samar,Eid, Samar,Najjar, Fadia,Macé, Aurélie,Rivilla, Ivan,Cossío, Fernando P.,Dorcet, Vincent,Roisnel, Thierry,Carreaux, Fran?ois

, (2021/11/22)

In a first instance, the effect of the microwave irradiation on the 1,3-Dioxa-[3,3]-sigmatropic rearrangement of aryl allylic carbamates was investigated. Under these new conditions, the reaction acceleration was clearly highlighted compared to convention

1,3-Dioxa-[3,3]-sigmatropic Oxo-Rearrangement of Substituted Allylic Carbamates: Scope and Mechanistic Studies

Agirre, Maddalen,Henrion, Sylvain,Rivilla, Ivan,Miranda, José I.,Cossío, Fernando P.,Carboni, Bertrand,Villalgordo, José M.,Carreaux, Fran?ois

, p. 14861 - 14881 (2019/01/04)

An unexpected 1,3-dioxa-[3,3]-sigmatropic rearrangement during the treatment of aryl- and alkenyl-substituted allylic alcohols with activated isocyanates is reported. The reorganization of bonds is highly dependent on the electron density of the aromatic
