149228-69-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 149228-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,2,2 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 149228-69:
(8*1)+(7*4)+(6*9)+(5*2)+(4*2)+(3*8)+(2*6)+(1*9)=153
153 % 10 = 3
So 149228-69-3 is a valid CAS Registry Number.

Asymmetric induction in cyclohexadienones carrying α-D-glucopyranosyl moiety

Yajima, Saki,Saitoh, Tsuyoshi,Kawa, Kohei,Nakamura, Kensuke,Nagase, Hiroshi,Einaga, Yasuaki,Nishiyama, Shigeru

, p. 8428 - 8435 (2016)

Cyclohexadienone derivatives possessing α-D-glucopyranosyl moiety were designed and synthesized using chemical oxidation or electrochemical oxidation with boron-doped diamond electrode in the final stage. In the chiral induction studies, catalytic hydroge

Aryl C-glycosides from O-glycosyltrichloroacetimidates and phenol derivatives with trimethylsilyl trifluoromethanesulfonate (TMSOTf) as the catalyst

Mahling,Schmidt

, p. 325 - 328 (2007/10/02)

The reaction of O-(2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl)trichloracetimidate (1), as glycosyl donor with phenol and naphthol derivatives 2a-d and 2f-h, as glycosyl acceptors, furnished in the presence of catalytic amounts of TMSOTf the corresponding o-hydroxyaryl C-β-D-glucopyranosides 3a-d, f-h regio- and stereoselectively. The less reactive 4-methoxyphenol (2e), α-naphthol (2i), the hydroxy substituted coumarines 2j, k and the flavone 2l afforded under these conditions O-glycosides 5e, i-l. Hydrogenolytic O-debenzylation of 3a,b,d afforded compounds 4a,b,d.
