Check Digit Verification of cas no

The CAS Registry Mumber 88230-04-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,3 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 88230-04:
(7*8)+(6*8)+(5*2)+(4*3)+(3*0)+(2*0)+(1*4)=130
130 % 10 = 0
So 88230-04-0 is a valid CAS Registry Number.

New C2-symmetrical 1,2-diphosphanes for the efficient rhodium-catalyzed asymmetric hydroboration of styrene derivatives

Demay, Steandphane,Volant, Florence,Knochel, Paul

, p. 1235 - 1238 (2007/10/03)

A double [2,3] sigmatropic rearrangement enables the fast synthesis of novel C2-symmetrical 1,2-diphosphanes in good yields. These phosphanes (for example, 1; c-Hex = cyclohexyl) are highly efficient ligands for the rhodium-catalyzed asymmetric hydroboration of a wide variety of styrenes (see scheme). cod = 1,5-cyclooctadiene; DME = 1,2-dimethoxyethane.

Hydroxyhalogenations of acyloxycyclohex-2-enes. Part 3. Iterative 1,2-hydroxyiodination of acetoxycyclohex-2-ene: Preparation of tetraacetyl conduritol D

Bange, Johannes,Haughan, Alan F.,Knight,Sweeney, Joseph

, p. 1039 - 1046 (2007/10/03)

Compound 22, the tetraacetyl derivative of conduritol D, has been synthesized by repeated hydroxyiodination reactions in nine steps from acetoxycyclohex-2-ene.

Diastereospecific Hydroxyiodination of 1-Acetoxycyclohex-2-ene via Intramolecular Delivery of Oxygen

Bange, Johannes,Haughan, Alan F.,Sweeney, J. B.

, p. 1405 - 1408 (2007/10/02)

The previously unreported reaction of N-iodosuccinimide with acetoxycyclohex-2-ene to give monoacetates of 3-iodocyclohexane-1,2-diols is diastereospecific.
