Check Digit Verification of cas no

The CAS Registry Mumber 357418-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,4,1 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 357418-50:
(8*3)+(7*5)+(6*7)+(5*4)+(4*1)+(3*8)+(2*5)+(1*0)=159
159 % 10 = 9
So 357418-50-9 is a valid CAS Registry Number.

New entry to the enantioselective formation of substituted cyclohexenes bearing an all-carbon quaternary stereogenic center

Komine, Keita,Urayama, Yasuhiro,Hosaka, Taku,Fukuda, Hayato,Hatakeyama, Susumi,Ishihara, Jun

supporting information, p. 273 - 281 (2020/02/04)

Enantioselective formation of cyclohexene derivatives bearing an all-carbon quaternary stereogenic center is described. The racemic cyclohexenes are readily transformed to chiral substituted cyclohexenes in good yield with excellent enantioselectivity and diastereoselectivity by a palladium-mediated deracemization. The resulting products are promising synthetic intermediates of biologically active natural products. This protocol provides us with a new entry to the concise and scalable synthesis of multifunctionalized compounds.

Enantioselective Diels-Alder reactions of optically active (buta-1,3-dien-2-yl)(salen)cobalt(iii) complexes

Chapman, John J.,Day, Cynthia S.,Welker, Mark E.

, p. 2273 - 2282 (2007/10/03)

The syntheses of two optically active (buta-1,3-dien-2-yl)(salen)Co complexes are reported. These dienyl complexes undergo Diels-Alder reactions with high enantioselectivity with a variety of dienophiles. One of the (salen)Co-substituted Diels-Alder cyclo

Enones with Strained Double Bonds. 8. The Bicyclooctane Systems

House, Herbert O.,Haack, John L.,McDaniel, William C.,VanDerveer, Don

, p. 1643 - 1654 (2007/10/02)

The bicyclic enones bicyclooct-1-en-3-one (4) and 1-methylbicyclooct-5(6)-en-7-one (5) have been generated from various precursors and trapped by the addition of nucleophiles such as MeOH, PhSeH, or H2O.The bridgehead enone 5 has also been trapped as its cycloadduct 31 with furan.Pyrolysis of this cycloadduct 31 reformed the bridgehead enone 5 that was trapped as the cycloadduct 32.Related bridgehead enones 35 and 47 have also been generated as intermediates leading to products with bridgehead methoxy substituents.
