544686-93-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 544686-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,4,6,8 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 544686-93:
(8*5)+(7*4)+(6*4)+(5*6)+(4*8)+(3*6)+(2*9)+(1*3)=193
193 % 10 = 3
So 544686-93-3 is a valid CAS Registry Number.

Claisen Rearrangements of Enantiomerically Pure C3-(Acyloxy)-(E)-vinylsilanes
Sparks, Michelle A.,Panek, James S.
, p. 3431 - 3438 (2007/10/02)
The Ireland ester Claisen rearrangement of chiral (R)- and (S)-(acyloxy)-(E)-vinylsilanes gives access to a wide range of α-chiral-β-silyl-(E)-hexenoic acids with useful levels of diastereoselectivity for both the 2,3-syn and 2,3-anti diastereomers as ill
