844867-20-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 844867-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,8,6 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 844867-20:
(8*8)+(7*4)+(6*4)+(5*8)+(4*6)+(3*7)+(2*2)+(1*0)=205
205 % 10 = 5
So 844867-20-5 is a valid CAS Registry Number.

Synthesis of postulated molecular probes: Stereoselective free-radical-mediated C-glycosylation in tandem with hydrogen transfer

Guindon, Yvan,Bencheqroun, Mohammed,Bouzide, Abderrahim

, p. 554 - 558 (2005)

Reported herein is a strategy employing an addition reaction in tandem with a hydrogen-transfer reaction for the elaboration of C-glycoside-based sialyl Lewis X (sLeX) analogues. Significant stereocontrol was noted when alkyl radicals were reacted with a series of alkoxytaconates. Transition states were proposed to explain the obtained selectivity. Further reaction between an anomeric-centered fucosyl-derived radical and a galactosylated hydroxytaconate provided easy access to C,O-diglycosides as mimics of sLeX. In this case, two 1,3-distant stereocenters were created with high diastereoselectivity using free radical intermediates in a tandem process.
