561319-11-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 561319-11-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,1,3,1 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 561319-11:
(8*5)+(7*6)+(6*1)+(5*3)+(4*1)+(3*9)+(2*1)+(1*1)=137
137 % 10 = 7
So 561319-11-7 is a valid CAS Registry Number.

Facile synthesis, antimicrobial and antiviral evaluation of novel substituted phenyl 1,3-thiazolidin-4-one sulfonyl derivatives

Mandal, Milan Kumar,Ghosh, Swagatika,Naesens, Lieve,Bhat, Hans Raj,Singh, Udaya Pratap

, (2021/07/17)

A series of novel substituted phenyl 1, 3-thiazolidin-4-one sulfonyl derivatives 5 (a-t) were synthesized and screened for their in-vitro anti-microbial and anti-viral activity. The result of the anti-microbial assay demonstrated compounds 5d, 5f, 5g, 5h,

Enantioselective Aza-Reformatsky Reaction with Ketimines

Maestro, Aitor,Martinez De Marigorta, Edorta,Palacios, Francisco,Vicario, Javier

supporting information, p. 9473 - 9477 (2019/11/28)

Here, an enantioselective aza-Reformatsky reaction using acyclic ketimine substrates is presented. Using α-phosphorated ketimines as electrophilic substrates and a simple BINOL-derived ligand, phosphorated analogues of aspartic acid holding chiral tetrasubstituted carbons are efficiently obtained with excellent enantioselectivity through an asymmetric organocatalytic Reformatsky-type reaction. The phosphorated analogues of aspartic acid have been used for the synthesis of phosphorus-containing enantiopure tetrasubstituted β-lactams.

Formation of: N -sulfonyl imines from iminoiodinanes by iodine-promoted, N-centered radical sulfonamidation of aldehydes

Hopkins, Megan D.,Scott, Kristina A.,Demier, Brettany C.,Morgan, Heather R.,Macgruder, Jesse A.,Lamar, Angus A.

, p. 9209 - 9216 (2017/11/14)

A mild and operationally convenient formation of synthetically valuable N-sulfonyl imines from a range of aryl aldehydes by reaction with iminoiodinanes (PhINZ) and I2 has been developed. According to mechanistic experiments described within, the reaction is speculated to proceed through an unconventional light-promoted, N-centered radical (NCR) pathway involving a N,N-diiodosulfonamide reactive species. This method not only provides a new pathway toward the production of activated imines, but also serves as an example of a non-traditional means of carbonyl activation via an NCR species.
