790294-90-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 790294-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,0,2,9 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 790294-90:
(8*7)+(7*9)+(6*0)+(5*2)+(4*9)+(3*4)+(2*9)+(1*0)=195
195 % 10 = 5
So 790294-90-5 is a valid CAS Registry Number.

Asymmetric oxidation of 3-alkyl-1,2-cyclopentanediones. Part 3: Oxidative ring cleavage of 3-hydroxyethyl-1,2-cyclopentanediones: Synthesis of α-hydroxy-γ-lactone acids and spiro-γ-dilactones

Paju, Anne,Kanger, Tonis,Niitsoo, Olivia,Pehk, Tonis,Mueuerisepp, Aleksander-Mati,Lopp, Margus

, p. 2393 - 2399 (2003)

A Ti(OiPr)4/diethyl tartrate/tBuOOH complex oxidizes 3-hydroxyethyl-1,2-cyclopentanediones, resulting in hydroxylated/ring cleavage products - lactone acids of high enantioselectivity (up to 95% ee) with good yields (up to 75%). These compounds are converted into chiral spiro-γ-dilactones in good yield.
