Check Digit Verification of cas no

The CAS Registry Mumber 75500-04-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,0 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75500-04:
(7*7)+(6*5)+(5*5)+(4*0)+(3*0)+(2*0)+(1*4)=108
108 % 10 = 8
So 75500-04-8 is a valid CAS Registry Number.

Iridium-Catalyzed β-C(sp2)?H Borylation of Enamides – Access to 3,3-Dihalogeno-2-methoxypiperidines

Gillaizeau, Isabelle,Dondasse, Isma?l,Nicolas, Cyril,Mimoun, Liliane,Sukach, Volodymyr,Meudal, Hervé

supporting information, (2022/02/07)

An efficient catalytic preparation of synthetically useful new β-borylated enamides was achieved under relatively mild conditions via a regioselective iridium-catalyzed C(sp2)?H borylation. The method features broad substrate scope, good functi

Use of 1,3-dibenzyl-dihydrouracil in the chain extension of 2,3-O-isopropylidene-D-glyceraldehyde

Ulgheri, Fausta,Bacsa, John,Nassimbeni, Luigi,Spanu, Pietro

, p. 671 - 675 (2007/10/03)

The aldol-type addition of 1,3-dibenzyl-dihydrouracil 2 to 2,3-O-isopropylidene-D-glyceraldehyde 3 was examined in different solvents and under Lewis acid catalysis in order to establish the stereochemical preferences. A stereodivergent synthesis of 5-trihydroxypropyl-dihydrouracil derivatives 4 and its C-5 epimer 5 was realized. The synthesis of ureido polyols 8 and 10 was obtained via the reductive ring opening of the templates 4 and 5.
