Check Digit Verification of cas no

The CAS Registry Mumber 122517-81-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,5,1 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 122517-81:
(8*1)+(7*2)+(6*2)+(5*5)+(4*1)+(3*7)+(2*8)+(1*1)=101
101 % 10 = 1
So 122517-81-1 is a valid CAS Registry Number.

Osmium tetroxide-(QN)2 PHAL in an ionic liquid: A highly efficient and recyclable catalyst system for asymmetric dihydroxylation of olefins

Song, Choong Eui,Jung, Da-Un,Roh, Eun Joo,Lee, Sang-Gi,Chi, Dae Yoon

, p. 3038 - 3039 (2002)

In Os-catalysed asymmetric dihydroxylation using NMO as a co-oxidant, the combination of an ionic liquid and the new bis-cinchona alkaloid 2 generated in situ from (QN)2PHAL during reaction provided a simple and practical approach to the recycling of both catalytic components (osmium tetroxide and chiral ligand).

Catalytic asymmetric dihydroxylation of olefins with recyclable osmate-exchanged chloroapatite catalyst

Dehury, Sanjay K.,Hariharakrishnan

, p. 2493 - 2496 (2007/10/03)

An osmate-exchanged chloroapatite (CAP-OsO4) catalyst was prepared by an ion-exchange technique. CAP-OsO4 efficiently catalyses asymmetric dihydroxylation of olefins including α,β-unsaturated esters and amides to afford the corresponding diols in high yields and enantioselectivities. The catalyst was reused for several cycles with consistent activity.

Asymmetric syn-Dihydroxylation of β-Substituted (2R)-N-(α,β-Enoyl)bornane-10,2-sultams

Raczko, Jerzy,Achmatowicz, Michael,Jezewski, Artur,Chapuis, Christian,Urbanczyk-Lipkowska, Zofia,Jurczak, Janusz

, p. 1264 - 1276 (2007/10/03)

Variously β-substituted (2R)-N-[(E)-α,β-enoyl]bornane-10,2-sultams were oxidized with OsO4/4-methylmorpholine 4-oxide in a highly stereoselective manner. In all cases, the attack occurred on the C(α)-re face. The absolute configurations of all
