90054-63-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90054-63-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,5 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90054-63:
(7*9)+(6*0)+(5*0)+(4*5)+(3*4)+(2*6)+(1*3)=110
110 % 10 = 0
So 90054-63-0 is a valid CAS Registry Number.

A MILD AND VARIABLE SYNTHESIS OF α-KETOESTERS
Reetz, M. T.,Heimbach, H.,Schwellnus, K.
, p. 511 - 514 (2007/10/02)
The ZnCl2 promoted addition of 1,2-diethoxy-1,2-disilyloxyethylene 1 with electrophiles such as aldehydes, ketones, α,β-unsaturated ketones or tertiary alkyl halides allows for a simple synthesis of α-ketoesters.
