3254-32-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3254-32-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,5 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3254-32:
(6*3)+(5*2)+(4*5)+(3*4)+(2*3)+(1*2)=68
68 % 10 = 8
So 3254-32-8 is a valid CAS Registry Number.

Boronic esters as protective groups in carbohydrate chemistry: processes for acylation, silylation and alkylation of glycoside-derived boronates

Mancini, Ross S.,Lee, Jessica B.,Taylor, Mark S.

, p. 132 - 143 (2016/12/27)

Procedures for selective installation of acyl, silyl ether and para-methoxybenzyl (PMB) ether groups to glycoside substrates have been developed, employing phenylboronic esters as protected intermediates. The sequence of boronic ester formation, functiona

A concise total synthesis of cleistenolide

Reddy, A. Bal,Kumara Swamy,Yadav, Jhillu Singh

, p. 788 - 790 (2016/07/29)

A concise total synthesis of cleistenolide has been achieved from D-glucose. The synthesis of cleistenolide proceeds in six steps from D-glucose diacetonide in 42.5% overall yield. Selective benzoylation and Still-Gennari olefination are the key reactions involved in the synthesis.

Control of regioselectivity in reactions of dialkylstannylene acetals. Part I. A dramatic reversal of regioselectivity in mono-p-toluenesulfonation reactions

Kong, Xianqi,Grindley, T. Bruce

, p. 2396 - 2404 (2007/10/02)

The regioselectivities of p-toluenesulfonation reactions of dialkylstannylene acetals obtained from a number of carbohydrate-derived terminal 1,2-diols in the absence of added nucleophiles have been explored as functions of the carbohydrate structure, the
