99298-07-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99298-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,9 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99298-07:
(7*9)+(6*9)+(5*2)+(4*9)+(3*8)+(2*0)+(1*7)=194
194 % 10 = 4
So 99298-07-4 is a valid CAS Registry Number.

Archaebacterial Isoprenoids. Synthesis of 2,3-Di-O-phytanyl-sn-glycerol and Its 1,2-Isomer

Aoki, Tadashi,Poulter, C. Dale

, p. 5634 - 5636 (1985)

2,3-Di-O-phytanyl-sn-glycerol (1), the major ether-lipid component of most archaebacterial membranes, and its 1,2-isomer (2) were synthesized in good overall yields from 3-O-benzyl-sn-glycerol (3).The 1-position of 3 was blocked selectively with tert-buty

Synthesis of (R)- and (S)-oxymethylmorpholine derivatives

Lee, Chi-Wan,Lee, Seok Jong

, p. 559 - 563 (2007/10/03)

(S)-N-benzyl-3-tert-butyldiphenylsilyloxymethylmorpholine and (R)-N- benzyl-3-benzyloxymethylmorpholine are synthesized starting from (R)-1- benzylglycerol.

Chiral environment specifically induced by metal ion: Asymmetric α- alkylation of α-amino esters using pyridoxal derivatives having a chiral ionophore function

Miyashita, Kazuyuki,Miyabe, Hideto,Tai, Kuninori,Kurozumi, Chiaki,Iwaki, Hiroshi,Imanishi, Takeshi

, p. 12109 - 12124 (2007/10/03)

Stereoselective alkylation of aldimines, prepared from α-amino esters and pyridoxal models having an ionophoric side-chain composed of a chiral glycerol structure, proceeded in the presence of Li+ or Na+ to afford α,α-dialkyl amino esters after acidic hydrolysis. Both the structure of the side chain and the metal ion were found to be in relation with the stereoselectivity, affording the highest stereoselectivity when the side- chain having a 2-naphthylmethoxy group and a methoxy group at the respective 3'- and 2'-positions was employed in the presence of Na+.
