42245-58-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42245-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,2,4 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 42245-58:
(7*4)+(6*2)+(5*2)+(4*4)+(3*5)+(2*5)+(1*8)=99
99 % 10 = 9
So 42245-58-9 is a valid CAS Registry Number.

STEREOSELECTIVE SYNTHESIS OF METHOXY SUBSTITUTED 2,3-DIBENZYL-γ-BUTYROLACTONES USING ORGANIC PHOSPHONATES AS INTERMEDIATES

Compagnone, Reinaldo S.,Suarez, Alirica

, p. 35 - 38 (2007/10/02)

A stereoselective, short and convergent synthesis of methoxy substituted 2,3-dibenzyl-γ-butyrolactones was developed using organic phosphonates as key intermediates.

Stereoselective synthesis of methoxy substituted 2,3-dibenzylbutyrolactones via organic phosphonates

Compagnone,Suarez

, p. 3041 - 3051 (2007/10/02)

A highly convergent, short and stereoselective synthesis of a series of methoxy substituted 2,3-dibenzylbutyrolactones was achieved using a Horner-Wadsworth-Emmons (HWE) reaction as the key step in overall yields above 32%.
