132559-56-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132559-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,5 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132559-56:
(8*1)+(7*3)+(6*2)+(5*5)+(4*5)+(3*9)+(2*5)+(1*6)=129
129 % 10 = 9
So 132559-56-9 is a valid CAS Registry Number.

The mechanistic study and synthetic applications of the base treatment in the ozonolytic reactions

Hon, Yung-Son,Lin, Sheng-Wun,Lu, Ling,Chen, Yao-Jung

, p. 5019 - 5034 (1995)

The E1cb mechanism is the overwhelming process in the reaction of bases and ozonides. As a quenching agent in the ozonolysis of a variety of alkenes, the reactions involving triethylamine often gave better yields and proceeded faster than those involving methyl sulfide. On the other hand, in the presence of 4 A molecular sieves, the secondary amines reacted with mono- and 1,1-di-substituted ozonides to afford the reductive amination products in high yields. The formation of ammonium formate in the reaction mixture also supported the E1cb mechanism in the reaction of ozonide and amine.

The Reaction of Ozonides from Mono-substituted Alkenes with Stabilized Phosphorus Ylides

Hon, Yung-Son,Lu, Ling,Li, Shyh-Yuan

, p. 1627 - 1628 (2007/10/02)

Ozonides derived from mono-substituted alkenes react with methyl (triphenylphosphoranylidene)acetate or (triphenylphosphoranylidene)acetophenone to form trans-α,β-unsaturated esters or ketones, respectively, in high yields.
