35387-94-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 35387-94-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,3,8 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 35387-94:
(7*3)+(6*5)+(5*3)+(4*8)+(3*7)+(2*9)+(1*4)=141
141 % 10 = 1
So 35387-94-1 is a valid CAS Registry Number.

Expeditious synthesis of benzopyrans via lewis acid-catalyzed C-H functionalization: Remarkable enhancement of reactivity by an ortho substituent

Mori, Keiji,Kawasaki, Taro,Sueoka, Shosaku,Akiyama, Takahiko

supporting information; experimental part, p. 1732 - 1735 (2010/09/05)

An expeditious construction of a benzopyran skeleton via Lewis acid-catalyzed C-H functionalization was achieved. In this process, a [1,5] hydride shift and 6-endo cyclization successively occurred to give benzopyrans. The presence of substituents ortho to the alkoxy group significantly enhanced the reactivity, affording the desired compounds in excellent chemical yields with short reaction times.

Synthesis of the spirocyclic cyclohexadienone ring system of the schiarisanrins.

Coleman,Guernon,Roland

, p. 277 - 280 (2007/10/03)

[structure: see text] Studies on the synthesis of the spirocyclic cyclohexadienone ring system 2 of the schiarisanrin family of natural products 1 are described and were based on the Lewis acid-promoted C-alkylation of the corresponding phenolic precursor.
