Check Digit Verification of cas no

The CAS Registry Mumber 177559-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,5,5 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 177559-01:
(8*1)+(7*7)+(6*7)+(5*5)+(4*5)+(3*9)+(2*0)+(1*1)=172
172 % 10 = 2
So 177559-01-2 is a valid CAS Registry Number.

Manganese-Based Contrast Agents for Magnetic Resonance Imaging of Liver Tumors: Structure-Activity Relationships and Lead Candidate Evaluation

Wang, Junfeng,Wang, Huan,Ramsay, Ian A.,Erstad, Derek J.,Fuchs, Bryan C.,Tanabe, Kenneth K.,Caravan, Peter,Gale, Eric M.

, p. 8811 - 8824 (2018)

Gd-based MRI contrast agents (GBCAs) have come under intense regulatory scrutiny due to concerns of Gd retention and delayed toxicity. Three GBCAs comprising acyclic Gd chelates, the class of GBCA most prone to Gd release, are no longer marketed in Europe

Acid-catalyzed rearrangement of 1-benzyl-2-methyl-3-piperidone to 1-benzyl-2-acetylpyrrolidine

Zhao, Shengyin,Jeon, Heung-Bae,Nadkarni, Durgesh V.,Sayre, Lawrence M.

, p. 6361 - 6369 (2007/10/03)

We report that 1-benzyl-2-methyl-3-piperidone, conveniently prepared from 3-hydroxy-2-methylpyridine, undergoes rearrangement to 1-benzyl-2-acetylpyrrolidine in aqueous 6 N HCl at reflux. Studies showing that the 2,2-dimethyl analog is inert under the same conditions support a mechanism of reversible tautomeric equilibria via ring-opened intermediates, one of which was independently synthesized and shown to be a kinetically competent intermediate to product.

Indolizine SPLA2inhibitors

-

Page/Page column 63, (2010/11/30)

A class of novel indolizine-1-functional compounds and indolizine-3-functional compounds is disclosed together with the use of such indolizine compounds for inhibiting sPLA2mediated release of fatty acids for treatment of conditions such as septic shock. The compounds are indolizine-1-acetamides, indolizine-1-acetic acid hydrazides, indolizine-1-glyoxylamides, indolizine-3-acetamides, indolizine-3-acetic acid hydraxides, and indolizine-3-glyoxylasides.
