131509-99-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131509-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131509-99:
(8*1)+(7*3)+(6*1)+(5*5)+(4*0)+(3*9)+(2*9)+(1*9)=114
114 % 10 = 4
So 131509-99-4 is a valid CAS Registry Number.

Asymmetric [2 + 2] cycloaddition reaction catalyzed by a chiral titanium reagent

Narasaka, Koichi,Hayashi, Yujiro,Shimadzu, Hideshi,Niihata, Shigeo

, p. 8869 - 8885 (2007/10/02)

In the presence of certain Lewis acids, alkenes containing an alkylthio group (for example, ketene dithioacetals, alkenyl sulfides, alkynyl sulfides, and allenyl sulfides) react with electron deficient olefins to give the corresponding cyclobutane, cyclobutene, or methylene cyclobutane derivatives. By employing a chiral titanium catalyst generated in situ from dichlorodiisopropoxytitanium and a tartrate-derived chiral diol, the [2 + 2] cycloaddition reaction proceeds with high enantioselectivity.

Ene Reaction of Allenyl Sulfides with Aldehydes and Schiff's Bases Catalyzed by Lewis Acids

Hayashi, Yujiro,Shibata, Takanori,Narasaka, Koichi

, p. 1693 - 1696 (2007/10/02)

Ene reaction proceeds between α-alkyallenyl sulfides and enophiles such as aldehydes and Schiff's bases in the presence of Lewis acid to afford various 1,3-dienes.
