122518-92-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122518-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,5,1 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 122518-92:
(8*1)+(7*2)+(6*2)+(5*5)+(4*1)+(3*8)+(2*9)+(1*2)=107
107 % 10 = 7
So 122518-92-7 is a valid CAS Registry Number.

Core structure of eremophilanes and bakkanes through niobium catalyzed Diels-Alder reaction: Synthesis of (±)-bakkenolide A

Constantino, Mauricio G.,De Oliveira, Kleber T.,Polo, Ellen C.,Da Silva, Gil V. J.,Brocksom, Timothy J.

, p. 9880 - 9883 (2007/10/03)

A suitable intermediate for the synthesis of eremophilanes and bakkanes was prepared by a highly regioselective and stereoselective one-step synthesis through a niobium catalyzed Diels-Alder reaction. As a demonstration of the versatility of this intermed

Regiocontrol of radical cyclization by Lewis acids. Efficient synthesis of optically active functionalized cyclopentanes and cyclohexanes

Kim, Kwangho,Okamoto, Sentaro,Sato, Fumie

, p. 67 - 69 (2007/10/03)

(equation presented) Treatment of α-alkylidenelactones 3a-d with Bu3SnH and a catalytic amount of Et3B effected a 5-exo radical cyclization preferentially to provide the corresponding 1 and 2 in a ratio of 70:30 to 100:0. Meanwhile,

An Approach to the Bakkanes. A Short, Stereocontrolled Total Synthesis of (+/-)-Bakkenolide A

Greene, Andrew E.,Depres, Jean-Pierre,Coelho, Fernando,Brocksom, Timothy J.

, p. 3943 - 3945 (2007/10/02)

A stereoselective total synthesis of (+/-)-bakkenolide A (fukinanolide) has been efficiently achieved in six steps.
