Check Digit Verification of cas no

The CAS Registry Mumber 865200-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,5,2,0 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 865200-99:
(8*8)+(7*6)+(6*5)+(5*2)+(4*0)+(3*0)+(2*9)+(1*9)=173
173 % 10 = 3
So 865200-99-3 is a valid CAS Registry Number.

Macrocyclic receptors containing sucrose skeleton

Jarosz, S?awomir,Listkowski, Arkadiusz,Lewandowski, Bartosz,Ciunik, Zbigniew,Brzuszkiewicz, Anna

, p. 8485 - 8492 (2007/10/03)

Crown ether analogues with incorporated sucrose unit were prepared by reaction of 1′,2,3,3′,4,4′-hexa-O-benzylsucrose with polyethylene ditosylates in up to 52% yield. Stability constants of their complexes with Li+, Na+, K+, NH 4+ were determined by the NMR titration method. The macrocycles were also tested as catalysts in the enantioselective Michael reaction, but with little success (ee up to only 22%). The macrocycle containing nitrogen in the ring was also prepared in good yield. All prepared macrocycles were easily converted into the free sucrose crowns (H2/Pd/C) without destroying the (very labile) glycosidic bond. The crystal structure of the selected receptor was determined.
