Check Digit Verification of cas no

The CAS Registry Mumber 141037-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,0,3 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 141037-91:
(8*1)+(7*4)+(6*1)+(5*0)+(4*3)+(3*7)+(2*9)+(1*1)=94
94 % 10 = 4
So 141037-91-4 is a valid CAS Registry Number.

Cross aldolization reactions in furane series by means of silyl enol ethers

Le Roux,Maraval,Borredon,Gaspard-Iloughmane,Dubac

, p. 1053 - 1054 (1992)

The catalytic cross aldol reaction between a silyl enol ether and an aldehyde has been applied to the furane series giving the ketols RCOCH2CHOHR' (R or R' = 2-furyl). Good results (with no resinification or crotonisation) have been obtained using bismuth

Vanadyl species-catalyzed complementary β-oxidative carbonylation of styrene derivatives with aldehydes

Yang, Wen-Chieh,Weng, Shiue-Shien,Ramasamy, Anandhan,Rajeshwaren, Gobi,Liao, Yi-Ya,Chen, Chien-Tien

supporting information, p. 2385 - 2392 (2015/03/04)

A series of oxometallic species and metal acetylacetonates (acac) was examined as catalysts for oxidative carbonylation of styrene with benzaldehyde using t-butylhydroperoxide as the co-oxidant in warm acetonitrile. Among them, VO((acac)2 and vanadyl(iv) chloride were found to be the only catalyst class to achieve cross-coupling processes by judiciously tuning the ligand electronic attributes, leading to β-hydroxylation- and β-peroxidation-carbonylation of styrene, respectively, in a complementary manner. Mechanistic studies indicated that vanadyl-associated acyl radicals generated by t-butoxy radical-assisted, homolytic cleavage of the aldehyde C-H bond were involved in tandem processes with an exclusive syn diastereoselectivity in the case of β-methylstyrene.

Biomimetic hydrogenation: A reusable NADH co-enzyme model for hydrogenation of α,β-epoxy ketones and 1,2-diketones

Huang, Qiang,Wu, Ji-Wei,Xu, Hua-Jian

supporting information, p. 3877 - 3881 (2013/07/05)

A biomimetic method has been developed to transform α,β-epoxy ketones or 1,2-diketones into corresponding β-hydroxy ketones or α-hydroxy ketones using a catalytic amount of BNAH or BNA +Br-. The regeneration of BNAH or BNA+Br - is achieved by a mixture of HCOOH/Et3N. A radical mechanism is proposed to explain these observations.
