Check Digit Verification of cas no

The CAS Registry Mumber 16881-33-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,8 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16881-33:
(7*1)+(6*6)+(5*8)+(4*8)+(3*1)+(2*3)+(1*3)=127
127 % 10 = 7
So 16881-33-7 is a valid CAS Registry Number.

Thieme Chemistry Journal awardees - Where are they now? Scope of tyrosine O-arylations with boronic acids: Optimized synthesis of an orthogonally protected isodityrosine

Kilitoglu, Bahar,Arndt, Hans-Dieter

scheme or table, p. 720 - 723 (2009/08/07)

The Evans-Chan-Lam variant of the Ullman condensation has been explored to deliver O-arylated tyrosines and tyrosinyl peptides. Key modifications for success were the slow addition of boronic acids to the phenol-catalyst mixture. Selectivity and scope are investigated. Georg Thieme Verlag Stuttgart.

STEROID SPARING AGENTS AND METHODS OF USING SAME

-

Page/Page column 539; 552-559, (2010/02/14)

This invention relates generally to the use of a steroid sparing agent for the preparation of a medicament for the treatment of inflammatory bowel diseases (IBD), asthma, multiple sclerosis (MS), rheumatoid arthritis (RA), graft versus host disease (GVHD), host versus graft disease, and various spondyloarthropathies, comprising administering a steroid sparing immunoglobulin or small molecule composition to a patient in need thereof. The invention also relates generally to combination therapies for the treatment of these conditions.

Deprotection of t-butyl esters of amino acid derivatives by nitric acid in dichloromethane

Strazzolini, Paolo,Scuccato, Massimo,Giumanini, Angelo G.

, p. 3625 - 3633 (2007/10/03)

The extension of the deprotection procedure of t-butylated carboxyl function using HNO3 in CH2Cl2 to a number of appropriately selected N-Z- derivatives of natural amino acid esters was investigated. The method was found to work effectively with alanine, phenylalanine, serine and the dipeptide aspartame, but the reagent brought about a number of unwanted transformations with tyrosine, methionine and tryptophan. Suitable protection of functions present in the latter ones allowed selective ester dealkylation, but tyrosine underwent unavoidable fast preliminary ring nitration. 2000 Elsevier Science Ltd.
