Check Digit Verification of cas no

The CAS Registry Mumber 236406-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,6,4,0 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 236406-37:
(8*2)+(7*3)+(6*6)+(5*4)+(4*0)+(3*6)+(2*3)+(1*7)=124
124 % 10 = 4
So 236406-37-4 is a valid CAS Registry Number.

Copper(I)-catalyzed borylative exo -cyclization of alkenyl halides containing unactivated double bond

Kubota, Koji,Yamamoto, Eiji,Ito, Hajime

supporting information, p. 2635 - 2640 (2013/03/29)

A borylative exo-cyclization of alkenyl halides has been reported. The reaction includes the regioselective addition of a borylcopper(I) intermediate to unactivated terminal alkenes, followed by the intramolecular substitution of the resulting alkylcopper(I) moiety for the halide leaving groups. Experimental and theoretical investigations of the reaction mechanism have also been described. This reaction provides a new method for the synthesis of alkylboronates containing strained cycloalkyl structures from simple starting materials.

The invention relates to compounds represented by the general formula [I][wherein Ar means an aryl group or a heteroaryl group which may have a substitutive group selected from a group consisting of a halogen atom, a lower alkyl group and a lower alkoxy group; R1 means a C3-C6 cycloalkyl group which is substitutable with a fluorine atom; R2 and R4 mean hydrogen atoms, groups represented by -(A1)m-NH-B or the like; R3 and R5 mean hydrogen atoms, C1-C6 aliphatic hydrocarbon groups or the like which are substitutable with a lower alkyl group(s); n means 0 or 1; and X means an oxygen atom or a sulfur atom]. Compounds according to the invention, since they not only have potent selective antagonistic activity against muscarinic M3 receptors but also exhibit excellent oral activity, durability of action and pharmacokinetics, are very useful as safe and effective remedies against respiratory, urinary and digestive diseases with little adverse side effects.
