291282-27-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 291282-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,2,8 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 291282-27:
(8*2)+(7*9)+(6*1)+(5*2)+(4*8)+(3*2)+(2*2)+(1*7)=144
144 % 10 = 4
So 291282-27-4 is a valid CAS Registry Number.

Synthesis of caryophyllose. Use of n-BuLi/Na-O-t-Bu in the coupling of highly functionalized ketones and dithioacetals

Adinolfi, Matteo,Barone, Gaspare,Festa, Pasquale,Guariniello, Luigi,Iadonisi, Alfonso

, p. 4981 - 4985 (2007/10/03)

The C-4 branched monosaccharide caryophyllose 2a was synthesized by, convergent approach relying on the coupling of metalated dithioacetal 4b with ketone 3. Combined use of n-BuLi and t-Bu-ONa as deprotonation system for 4b turned out to be decisive for the success of this coupling. (C) 2000 Elsevier Science Ltd.
