1285537-44-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1285537-44-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,5,5,3 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1285537-44:
(9*1)+(8*2)+(7*8)+(6*5)+(5*5)+(4*3)+(3*7)+(2*4)+(1*4)=181
181 % 10 = 1
So 1285537-44-1 is a valid CAS Registry Number.

Highly diastereoselective C(sp3)i-C(sp) cross-coupling reactions between 1,3- and 1,4-substituted cyclohexylzinc reagents and bromoalkynes through remote stereocontrol

Thaler, Tobias,Guo, Li-Na,Mayer, Peter,Knochel, Paul

supporting information; experimental part, p. 2174 - 2177 (2011/04/25)

Under the influence: The use of the readily available and inexpensive orthophenantroline derivative neocuproine as a ligand in the generally applicable and highly stereoselective palladium-catalyzed title reaction results in diastereomeric ratios of up to 98:2. The method can be used for the synthesis of building blocks which may be relevant for the synthesis of liquid crystalline mesogens and their chiral dopants (see scheme, dba=trans,trans- dibenzylideneacetone).
