119237-86-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119237-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,3 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 119237-86:
(8*1)+(7*1)+(6*9)+(5*2)+(4*3)+(3*7)+(2*8)+(1*6)=134
134 % 10 = 4
So 119237-86-4 is a valid CAS Registry Number.

Synthesis of the mannopeptimycin disaccharide and its conjugation with 4-alkylidene-β-lactams

Adinolfi, Matteo,Giacomini, Daria,Iadonisi, Alfonso,Quintavalla, Arianna,Valerio, Silvia

experimental part, p. 2895 - 2899 (2009/04/06)

The disaccharide moiety of the antibiotic mannopeptimycin has been synthesized as a (N-phenyl)trifluoroacetimidate donor, the reactivity of which was tested in conjugation with a 4-alkylidene-β-lactam acceptor. Key steps of the synthesis were Bi(OTf)

Efficient installation of β-mannosides using a dehydrative coupling strategy

Codee, Jeroen D. C.,Hossain, Laila H.,Seeberger, Peter H.

, p. 3251 - 3254 (2007/10/03)

(Chemical Equation Presented) A new coupling procedure for the construction of the challenging β-mannosidic bond is described. Dehydrative mannosylation using 4,6-O-benzylidene mannopyranoses allows for the formation of β-mannosides in excellent yield. Th
