Check Digit Verification of cas no

The CAS Registry Mumber 299216-13-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,2,1 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 299216-13:
(8*2)+(7*9)+(6*9)+(5*2)+(4*1)+(3*6)+(2*1)+(1*3)=170
170 % 10 = 0
So 299216-13-0 is a valid CAS Registry Number.

A simple and efficient approach to the N-amination of oxazolidinones using monochloroamine

Huynh, Uyen,Uddin, Md. Nasir,Wengryniuk, Sarah E.,McDonald, Stacey L.,Coltart, Don M.

, p. 4799 - 4802 (2016)

Chiral nonracemic N-amino cyclic carbamates (ACCs) are important auxiliaries for certain asymmetric transformations. In the past they have been synthesized from oxazolidinones using methods that require the preparation and use of non-atom economical aminating agents that can be difficult to prepare, and often strong bases. In what follows we describe a mild and operationally simple method for the direct N-amination of oxazolidinones that use NH2Cl derived from commercial bleach.

A novel hydrazide type organocatalyst for enantioselective Diels-Alder reactions

Suzuki, Ichiro,Ando, Masafumi,Shimabara, Rumiko,Hirata, Ai,Takeda, Kei

supporting information; experimental part, p. 3033 - 3040 (2011/05/30)

The development of a new class of hydrazide type organocatalyst, (4R,5R)-1,3-bis(isopropylamino)-4,5-dihenylimidazolidin-2-one 2a, for enantioselective Diels-Alder reactions between cyclopentadiene and α,β-unsaturated aldehydes are presented. The new organocatalyst 2a promoted the reaction, affording Diels-Alder adducts in good yields with good levels of enantioselectivity.

Mn-mediated coupling of alkyl iodides and ketimines: A radical addition route to α,α-disubstituted α-aminoesters

Friestad, Gregory K.,Ji, An

scheme or table, p. 2311 - 2313 (2009/05/11)

(Chemical Equation Presented) Coupling of primary and secondary alkyl iodides with N-acylhydrazonoesters via Mn-mediated photolysis conditions affords access to tert-alkyl amines.
