Check Digit Verification of cas no

The CAS Registry Mumber 131179-09-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,7 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131179-09:
(8*1)+(7*3)+(6*1)+(5*1)+(4*7)+(3*9)+(2*0)+(1*9)=104
104 % 10 = 4
So 131179-09-4 is a valid CAS Registry Number.

Synthesis and structure-activity data of some new epibatidine analogues

Seerden, Jean-Paul G.,Tulp, Martin Th. M.,Scheeren, Hans W.,Kruse, Chris G.

, p. 2103 - 2110 (1998)

The high-pressure Diels-Alder reaction of N-carbomethoxypyrroles and phenyl vinyl sulfone affords versatile intermediates for the palladium-catalyzed preparation of new epibatidine analogues. Structure-activity relationships of new epibatidine analogues are presented. High affinities of K(i)=0.81 and 2.6nM for the [3H]-cytisine rat brain nicotinic acetylcholine binding sites were found for the 5-pyrimidinyl and the 5-(2-amino)-pyrimidinyl epibatidine analogues, respectively.

A Total Synthesis of (+/-)-Epibatidine

Clayton, Simon C.,Regan, Andrew C.

, p. 7493 - 7496 (1993)

A total synthesis of the potent non-opiate analgesic alcaloid epibatidine is described, in which the key step is reductive palladium-catalysed Heck-type coupling.The synthesis is concise (two steps from known compounds), highly convergent, and completely sttereoselective for the desired exo-isomer. - Key Words: Epibatidine, Analgesic, Alkaloid, Palladium-catalysed Coupling

Synthesis of 7-azabicyclo[2.2.1]heptane and 2-oxa-4-azabicyclo[3.3.1]non-3- ene derivatives by base-promoted heterocyclization of alkyl N-(cis(trans)-3, trans(cis)-4-dibromocyclohex-1-yl)carbamates and N-(cis(trans)-3,trans(cis)-4- dibromocyclohex-1-yl)-2

Gomez-Sanchez, Elena,Soriano, Elena,Marco-Contelles, Jose

, p. 8656 - 8670 (2008/03/12)

(Chemical Equation Presented) We have studied the base-promoted heterocyclization of alkyl N-(cis(trans)-3,trans(cis)-4-dibromocyclohex-1-yl) carbamates and N-(cis(trans)-3,trans(cis)-4-dibromocyclohex-1-yl)-2,2,2- trifluoroacetamides, investigating the e
