105445-49-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105445-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,4,4 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 105445-49:
(8*1)+(7*0)+(6*5)+(5*4)+(4*4)+(3*5)+(2*4)+(1*9)=106
106 % 10 = 6
So 105445-49-6 is a valid CAS Registry Number.

STEREOCHEMICALLY CONTROLLED SYNTHESIS OF UNSATURATED HYDROXY-ACIDS BY THE HORNER-WITTIG REACTION
Greeves, Nicholas,Warren, Stuart
, p. 259 - 262 (2007/10/02)
α-Ph2PO-Ketones containing OH and CO2R groups are stereoselectively reduced by NaBH4 under CeCl3 catalysis to give Horner-Wittig intermediates for the synthesis of E-isomers of unsaturated hydroxy-acids.
