771570-25-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 771570-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,1,5,7 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 771570-25:
(8*7)+(7*7)+(6*1)+(5*5)+(4*7)+(3*0)+(2*2)+(1*5)=173
173 % 10 = 3
So 771570-25-3 is a valid CAS Registry Number.

Sequential Suzuki/asymmetric aldol and Suzuki/Knoevenagel reactions under aqueous conditions

Gruttadauria, Michelangelo,Bivona, Lucia Anna,Lo Meo, Paolo,Riela, Serena,Noto, Renato

, p. 2635 - 2642 (2012)

Here we describe for the first time a sequential Suzuki/asymmetric aldol reaction. Such sequential approach was achieved through the combined use of an ionic liquid supported palladium catalyst and the organocatalyst trans-4-(2,2-diphenylacetoxy)proline. Suzuki and asymmetric aldol reactions were performed under aqueous conditions. The use of a palladium catalyst under basic conditions allowed also the first example of sequential Suzuki/Knoevenagel reaction. Reactions were carried out under aqueous conditions and products were isolated in good to high yields and, in the case of the Suzuki/aldol reaction, with diastereoselectivities up to 91:9 and enantioselectivities up to at least 99%.
