78845-10-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78845-10-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,4 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78845-10:
(7*7)+(6*8)+(5*8)+(4*4)+(3*5)+(2*1)+(1*0)=170
170 % 10 = 0
So 78845-10-0 is a valid CAS Registry Number.

A Synthetic Equivalent for the Butadienyl Carbonium Ion: Use of 4-(Trimethylsilyl)but-2-ynal for Preparation of 1,3-Dienes and Macroexpansion of Cyclic Ketones

Angoh, A. Gaetan,Clive, Derrick L. J.

, p. 534 - 536 (2007/10/02)

4-(Trimethylsilyl)but-2-ynal (3) is a synthetic equivalent for the butadienyl carbonium ion and can be used for preparation of terminal 1,3-dienes and for macroexpansion of cyclic ketones.

MACROEXPANSION METHODOLOGY; MEDIUM RING SYNTHESIS BASED ON AN EIGHT UNIT RING EXPANSION PROCESS

Wender, Paul A.,Sieburth McN., Scott,Petraitis, Joseph J.,Singh, Sunil K.

, p. 3967 - 3975 (2007/10/02)

Treatment of 1,2-(E,E)-di(1-buta-1,3-dienyl)cyclohexanol (21) with potassium hydride in tetrahydrofuran at room temperature resulted in the facile formation of a 14-membered ring dienolate which on kinetic protonation provided cyclotetradeca-3,5,7-trien-1-one.This novel rearrangement which provides the basis for an efficient, eight unit ring expansion method was also observed when 5,8-dimethyl-5-hydroxy-1,3,7,9-decapentaene (28), the acyclic analogue of 21, was treatad with potassium hydride in tetrahydrofuran.Methodology for the preparation of 21 and 28 including the preparation of 1-lithio-1,3-butadiene is also described.

MACROEXPANSION METHODOLOGY: AN EFFICIENT EIGHT UNIT RING EXPANSION

Wender, Paul A.,Sieburth, Scott McN.

, p. 2471 - 2474 (2007/10/02)

An efficient eight unit expansion method which is postulated to proceed by either a or consecutive sigmatropic shifts is described.
