Check Digit Verification of cas no

The CAS Registry Mumber 652990-14-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,2,9,9 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 652990-14:
(8*6)+(7*5)+(6*2)+(5*9)+(4*9)+(3*0)+(2*1)+(1*4)=182
182 % 10 = 2
So 652990-14-2 is a valid CAS Registry Number.

Synthesis of novel macrocyclic derivatives with a sucrose scaffold by the RCM approach

??czycka, Katarzyna,Jarosz, S?awomir

, p. 9216 - 9222 (2015)

1′2,3,3′4,4′-Hexa-O-benzylsucrose was esterified at both terminal positions with an unsaturated acid derived from d-glucose. Cyclization of the resulting di-olefin under the RCM conditions afforded the corresponding 21-membered macrocyclic unsaturated di-

Microwave-assisted protocols applied to the synthesis of 1′,2,3,3′,4,4′-Hexa-O-benzylsucrose

Raposo, Cláudia D.,Petrova, Krasimira T.,Barros, M. Teresa

, p. 3027 - 3036 (2014/11/07)

The sucrose derivative 1′,2,3,3′,4,4′-hexa-O- benzylsucrose is a key intermediate for the chemoselective synthesis of various useful materials, such as macrocycles, crown ether analogs, and polymers. Several strategies for the synthesis of this compound were explored by applying microwave-assisted protocols, thus permitting significant reductions of time and energy compared to other routes. The outcomes of the different approaches were compared and the optimal one, in terms of yield and reproducibility, was found to be the initial protection at the positions 6 and 6′, with tert-butyldiphenylsilylchloride (TBDPSCl) in the presence of 4-(dimethylamino)pyridine (4-DMAP) and pyridine as a solvent, then perbenzylation of the remaining hydroxyl groups, followed by selective deprotection of the TBDPS groups to obtain the title compound.

Synthesis of Macrocyclic Derivatives Containing a Sucrose Unit

Jarosz, Slwomir,Listkowski, Arkadiusz

, p. 753 - 763 (2007/10/03)

An efficient synthesis of 1′,2,3,3′4,4′-hexa-O- benzylsucrose (48% from sucrose) is presented. This diol was used for the preparation of crown ether-type analogs of various size macrocyclic rings with incorporated sucrose units.
