4356-66-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4356-66-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4356-66:
(6*4)+(5*3)+(4*5)+(3*6)+(2*6)+(1*6)=95
95 % 10 = 5
So 4356-66-5 is a valid CAS Registry Number.

Unexpected reactivity of diaryl α-diketones with thiazolium carbenes: Discovery of a novel multicomponent reaction for the facile synthesis of 1,4-thiazin-3-ones

Bertolasi, Valerio,Bortolini, Olga,Donvito, Adelaide,Fantin, Giancarlo,Fogagnolo, Marco,Giovannini, Pier Paolo,Massi, Alessandro,Pacifico, Salvatore

experimental part, p. 6579 - 6586 (2012/09/08)

Diaryl α-diketones do not undergo polarity reversal in the presence of (benzo)thiazolium carbenes but are engaged in a novel multicomponent reaction with water to efficiently give medicinally relevant 1,4-thiazin-3-one heterocycles. Three different sets of conditions have been optimized to furnish the title compounds in fair to excellent yields depending on the electronic properties of α-diketone aromatic substituents and thiazolium or benzothiazolium substrate. A plausible reaction mechanism is also proposed based on the isolation and characterization of the postulated key intermediate and isotopic labeling experiments.
