37457-08-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 37457-08-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,4,5 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 37457-08:
(7*3)+(6*7)+(5*4)+(4*5)+(3*7)+(2*0)+(1*8)=132
132 % 10 = 2
So 37457-08-2 is a valid CAS Registry Number.

2,4,6-Trichloro-1,3,5-triazine catalyzed chemoselective transthioacetalization of aldehyde acetals and oxathioacetals

Bandgar, Babasaheb P.,Joshi, Neeta S.,Bettigeri, Sampada V.

, p. 67 - 71 (2007/10/03)

A mild and efficient transthioacetalization of aldehyde acetals and oxathioacetals was carried out using 2,4,6-trichloro-1,3,5-triazine as a mild and inexpensive catalyst. Chemoselective transacetalization is impressive as aldehyde O,O- and O,S-acetals ar

Unprecedented polymer-supported π-acid: Synthesis and its application as a promoter to the monothioacetalization of acetals

Masaki, Yukio,Tanaka, Nobuyuki,Miura, Tsuyoshi

, p. 5799 - 5802 (2007/10/03)

A novel polymer was synthesized by copolymerization of styrene monomer bearing dicyanoketene acetal functionality and ethylene glycol dimethacrylate, and used successfully as a recyclable π-acid catalyst in monothioacetalization of aromatic, aliphatic, acyclic, and cyclic acetals with thiophenol and phenylthiotrimethylsilane.

A Convenient Method for the Transformation of Alkenyl Sulfides to 2-(Phenylthio)alkanenitriles, Homoallyl Sulfides, and Thioacetals

Takeda, Takeshi,Kaneko, Yuichiro,Nakagawa, Hitoshi,Fujiwara, Tooru

, p. 1963 - 1966 (2007/10/02)

2-(Phenylthio)alkanenitriles, homoallyl sulfides, and thioacetals were obtained in good yields by the reaction of alkenyl sulfides with the corresponding silyl nucleophiles via thionium ion intermediates.
