126338-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126338-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,3,3 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126338-55:
(8*1)+(7*2)+(6*6)+(5*3)+(4*3)+(3*8)+(2*5)+(1*5)=124
124 % 10 = 4
So 126338-55-4 is a valid CAS Registry Number.

EXTENSION OF THE HORNER-WITTIG REACTION TO THE SYNTHESIS OF E-ALKENES WITH CHIRAL SUBSTITUENTS: STEREOCHEMICAL CONTROL BY ACYL TRANSFER
Ayrey, Peter M.,Warren, Stuart
, p. 4581 - 4584 (2007/10/02)
Single crystalline diastereoisomers of hydroxyalkyl phosphine oxides (and hence functionalised E-alkenes) can be isolated, even when other chiral centres are present in the molecule, if they are made by acyl transfer.
