133323-26-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133323-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,2 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133323-26:
(8*1)+(7*3)+(6*3)+(5*3)+(4*2)+(3*3)+(2*2)+(1*6)=89
89 % 10 = 9
So 133323-26-9 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
