Check Digit Verification of cas no

The CAS Registry Mumber 1615737-65-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,5,7,3 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1615737-65:
(9*1)+(8*6)+(7*1)+(6*5)+(5*7)+(4*3)+(3*7)+(2*6)+(1*5)=179
179 % 10 = 9
So 1615737-65-9 is a valid CAS Registry Number.

Enantioselective synthesis of 1-vinyltetrahydroisoquinolines through palladium-catalysed intramolecular allylic amidation with chiral PhthalaPhos ligands

Pignataro, Luca,Marelli, Enrico,Gennari, Cesare,Ferraccioli, Raffaella

, p. 844 - 850 (2014)

The PhthalaPhos ligands, chiral BINOL monophosphites endowed with a phthalamide group, have been screened in the synthesis of 1- vinyltetrahydroisoquinolines by intramolecular palladium-catalysed asymmetric allylic amidation (AAA) of achiral tosylamidocarbonates. Identification of the best ligand followed by optimisation of the reaction conditions allowed the desired product to be obtained with up to 83% ee. Remarkably, the reaction is stereoconvergent, affording the same enantiomer of the desired product regardless of the geometry of the allylic carbonate's double bond, which allows, in principle, the use of E/Z mixtures.
