406674-56-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 406674-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,6,6,7 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 406674-56:
(8*4)+(7*0)+(6*6)+(5*6)+(4*7)+(3*4)+(2*5)+(1*6)=154
154 % 10 = 4
So 406674-56-4 is a valid CAS Registry Number.

Synthesis of highly reactive organosulfur compounds

Okazaki, Renji,Goto, Kei

, p. 414 - 418 (2002)

Application of novel bowl-type and dendrimer-type steric protection groups to the first synthesis of stable aromatic S-nitrosothiols is described. These compounds showed remarkable thermal stability whereas they easily reacted with appropriate reagents. X-ray crystallographic analysis established their structures, where the C-S-N-O linkage adopts only the syn conformation. Synthesis of a stable sulfenic acid by taking advantage of the bowl-type substituent is also delineated.

Synthesis, Structure, and Reactions of the First Stable Aromatic S-Nitrosothiol Bearing a Novel Dendrimer-Type Steric Protection Group

Goto, Kei,Hino, Yoko,Takahashi, Yusuke,Kawashima, Takayuki,Yamamoto, Gaku,Takagi, Nozomi,Nagase, Shigeru

, p. 1204 - 1205 (2007/10/03)

A stable aromatic S-nitrosothiol was synthesized by taking advantage of a novel dendrimer-type steric protection group, and its structure was determined by X-ray crystallographic analysis. Its reactions including oxidation to a stable S-nitrothiol are described.
