Check Digit Verification of cas no

The CAS Registry Mumber 29314-09-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,3,1 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29314-09:
(7*2)+(6*9)+(5*3)+(4*1)+(3*4)+(2*0)+(1*9)=108
108 % 10 = 8
So 29314-09-8 is a valid CAS Registry Number.

Highly Enantioselective Direct Synthesis of Endocyclic Vicinal Diamines through Chiral Ru(diamine)-Catalyzed Hydrogenation of 2,2′-Bisquinoline Derivatives

Ma, Wenpeng,Zhang, Jianwei,Xu, Cong,Chen, Fei,He, Yan-Mei,Fan, Qing-Hua

, p. 12891 - 12894 (2016)

An asymmetric hydrogenation of 2,2′-bisquinoline and bisquinoxaline derivatives, catalyzed by chiral cationic ruthenium diamine complexes, was developed. A broad range of chiral endocyclic vicinal diamines were obtained in high yields with excellent diastereo- and enantioselectivity (up to 93:7 dl/meso and >99 % ee). These chiral diamines could be easily transformed into a new class of chiral N-heterocyclic carbenes (NHCs), which are important but difficult to access.

Chemoselective One-Pot Synthesis of Functionalized Amino-azaheterocycles Enabled by COware

Clohessy, Thomas A.,Roberts, Alastair,Manas, Eric S.,Patel, Vipulkumar K.,Anderson, Niall A.,Watson, Allan J. B.

supporting information, p. 6368 - 6371 (2017/12/08)

Functionalized bicyclic amino-azaheterocycles are rapidly accessed in a one-pot cross-coupling/reduction sequence enabled by the use of COware. Incompatible reagents are physically separated in a single reaction vessel to effect two chemoselective transformations - Suzuki-Miyaura cross-coupling and heteroarene reduction. The developed method allows access to novel heterocyclic templates, including semisaturated Hedgehog and dual PI3K/mTOR inhibitors, which show enhanced physicochemical properties compared to their unsaturated counterparts.

METHOD OF PREPARING SILYLATIVE-REDUCED N-HETEROCYCLIC COMPOUND USING ORGANOBORON CATALYST

-

Paragraph 245; 246; 247; 248, (2016/06/06)

Provided is a method of preparing a silylative-reduced N-heterocyclic compound by reducing an N-heteraromatic compound including a sp2 hybridized nitrogen atom while simultaneously introducing a silyl group into a beta-position with respect to a nitrogen atom of the N-heteroaromatic compound, using a silane compound, in the presence of an organoboron catalyst.
