110352-59-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 110352-59-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,3,5 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 110352-59:
(8*1)+(7*1)+(6*0)+(5*3)+(4*5)+(3*2)+(2*5)+(1*9)=75
75 % 10 = 5
So 110352-59-5 is a valid CAS Registry Number.

High Diastereoselection in the Aldol Reaction of the Bistrimethylsilyl Enol Ether of Methyl Acetoacetate with 2-Benzyloxyhexanal: Synthesis of (-)-Pestalotin

Hagiwara, Hisahiro,Kimura, Katsuhiko,Uda, Hisashi

, p. 693 - 700 (2007/10/02)

Aldol condensation of the bistrimethylsilyl enol ether of methyl acetoacetate, compound 2, with 2-benzyloxyhexanal 3c affords highly selectively (99:1) the syn-aldol adduct 4c in the presence of titanium tetrachloride.The stereocontrolled synthesis of (-)-pestalotin 7 has been achieved.
