856015-17-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 856015-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,0,1 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 856015-17:
(8*8)+(7*5)+(6*6)+(5*0)+(4*1)+(3*5)+(2*1)+(1*7)=163
163 % 10 = 3
So 856015-17-3 is a valid CAS Registry Number.

A formal [3 + 3] cycloaddition reaction. 5. An enantioselective intramolecular formal aza-[3 + 3] cycloaddition reaction promoted by chiral amine salts

Gerasyuto, Aleksey I.,Hsung, Richard P.,Sydorenko, Nadiya,Slafer, Brian

, p. 4248 - 4256 (2007/10/03)

A detailed account on chiral secondary amine salt promoted enantioselective intramolecular formal aza-[3 + 3] cycloadditions is described here for the first time. The dependence of enantioselectivity on the structural feature of these chiral amines is tho

New Members of the Chiral Pool: β-Hydroxypiperidine Carboxylates from Baker's Yeast Reduction of the Corresponding Keto-esters

Knight, David W.,Lewis, Neil,Share, Andrew C.,Haigh, David

, p. 625 - 628 (2007/10/02)

Baker's yeast reductions of the keto-piperidinecarboxylates 2 and 6 leads to the corresponding hydroxy-esters 3 and 7a in good chemical yields and with >99percent d.e. and >93percent e.e. in both cases.
