Check Digit Verification of cas no

The CAS Registry Mumber 132902-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,0 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132902-42:
(8*1)+(7*3)+(6*2)+(5*9)+(4*0)+(3*2)+(2*4)+(1*2)=102
102 % 10 = 2
So 132902-42-2 is a valid CAS Registry Number.

Asymmetric henry reaction catalyzed by a chiral Cu(II) complex: A facile enantioselective synthesis of (S)-2-nitro-1-arylethanols

Reddy, Basi V. Subba,Reddy, Sankham Madhusudana,Manisha, Swain,Madan, Chinnala

experimental part, p. 530 - 535 (2011/06/17)

A catalytic asymmetric Henry reaction has been developed using a novel chiral Cu(II) complex derived from (R)-2-(diphenylmethanol)-l-(2-pyridylmethyl) pyrrolidine and copper(II) acetate in ethanol under mild conditions. The corresponding chiral 2-nitro-1-

Asymmetric Cyanosilylation of Ketones Catalyzed by Bifunctional Chiral N-Oxide Titanium Complex Catalysts

Shen, Yongcun,Feng, Xiaoming,Li, Yan,Zhang, Guolin,Jiang, Yaozhong

, p. 129 - 137 (2007/10/03)

A new bifunctional catalytic system based on chiral N-oxide titanium complexes has been used for the asymmetric cyanosilylation of ketones. Screening of a variety of chiral N-oxide metal complexes resulted in (1R,2S)-1-(2'-pyridylmethyl)-2-(diphenylhydroxymethyl)pyrrolidine N-oxide titanium complex, which gave O-TMS cyanohydrins in good yields with enantiometric excesses of up to 69 percent. A catalytic cycle based on experimental phenomena and studies was proposed to explain the origin of the asymmetric induction.

Asymmetric Catalysis, Part 91: Enantioselective Monophenylation of cis-1,2-Cyclopentanediol with Triphenylbismuth Diacetate and Chiral Copper(II) Complexes as Catalysts

Brunner, H.,Chuard, T.

, p. 1293 - 1300 (2007/10/02)

The monophenylation of cis-1,2-cyclopentanediol with triphenylbismuth diacetate in the presence of chiral Cu(II) complexes as catalysts gave cis-2-hydroxy-1-phenoxy-cyclopentane with enantiomeric excesses up to 38percent.The optically active ligands used were triamine derivatives of 2,6-bis(aminomethyl)pyridine and diamine derivatives of 2-(aminomethyl)pyridine.Selectivity in the monophenylation occurred only in the presence of the latter as auxiliary ligands. - Keywords.Enantioselective catalysis; Chiral Cu(II) complexes; Monophenylation; Triphenylbismuth diacetate; cis-1,2-Cyclopentanediol.
