70144-57-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70144-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,4 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70144-57:
(7*7)+(6*0)+(5*1)+(4*4)+(3*4)+(2*5)+(1*7)=99
99 % 10 = 9
So 70144-57-9 is a valid CAS Registry Number.

Carbohydrate-based N-heterocyclic carbenes for enantioselective catalysis

Henderson, Alexander S.,Bower, John F.,Galan, M. Carmen

, p. 9180 - 9183 (2015/02/19)

Versatile syntheses of C2-linked and C2-symmetric carbohydrate-based imidazol(in)ium salts from functionalised amino-carbohydrate derivatives are reported. The novel NHCs were ligated to [Rh(COD)Cl]2 and evaluated in Rh-catalysed asymmetric hydrosilylation of ketones with good yields and promising enantioselectivities.

Synthesis of monodeoxy and mono-O-methyl congeners of methyl β-d-mannopyranosyl-(1→2)-β-d-mannopyranoside for epitope mapping of anti-Candida albicans antibodies

Nycholat, Corwin M.,Bundle, David R.

experimental part, p. 1397 - 1411 (2009/12/06)

A panel of six complementary monodeoxy and mono-O-methyl congeners of methyl β-d-mannopyranosyl-(1→2)-β-d-mannopyranoside (1) were synthesized by stereoselective glycosylation of monodeoxy and mono-O-methyl monosaccharide acceptors with a 2-O-acetyl-gluco

ALKYLATION OF METHYL 4,6-O-BENZYLIDENE-α-D-GALACTOPYRANOSIDE

Grishkovets, V. I.,Chirva, V. Ya.

, p. 25 - 28 (2007/10/02)

The partial alkylation of methyl 4,6-benzylidene-α-D-galactopyranoside in dimethylformamide and dimethyl sulfoxide in the presence of barium oxide and hydroxide is described.It has been shown that methylation and benzylation lead predominantly to the 3-al
