104470-43-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 104470-43-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,7 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104470-43:
(8*1)+(7*0)+(6*4)+(5*4)+(4*7)+(3*0)+(2*4)+(1*3)=91
91 % 10 = 1
So 104470-43-1 is a valid CAS Registry Number.

Synthesis of (Trimethylsilyl)thiazoles and Reactions with Carbonyl Compounds. Selectivity Aspects and Synthetic Utility

Dondoni, Alessandro,Fantin, Giancarlo,Fogagnolo, Marco,Medici, Alessandro,Pedrini, Paola

, p. 1748 - 1761 (1988)

Synthetic routes to all possible regioisomeric mono- and bis(trimethylsilyl)thiazoles as well as to the tris(trimethylsilyl) derivative via lithiation-silylation sequences of the thiazole ring followed by selective protodesilylation in some cases are described. (Trimethylsilyl)thiazoles serve as thiazolyl donor synthons upon reaction with carbonyl compounds (ketenes, acyl chlorides, aldehydes) for the preparation of mono- and bis-substituted thiazoles in very good yields.Carbodesilylation occurs more readily at the 2- than 5-position, whereas no reaction takes place at the 4-position.A mechanism via a thiazolium 2-ylide as an intermediate is suggested for the carbodesilylation at the 2-position.
