253776-70-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 253776-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,7,7 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 253776-70:
(8*2)+(7*5)+(6*3)+(5*7)+(4*7)+(3*6)+(2*7)+(1*0)=164
164 % 10 = 4
So 253776-70-4 is a valid CAS Registry Number.

Regio- and diastereoselective aldol products through three-component coupling reactions of difiuoroboroxy fischer carbene molybdenum complexes

Barluenga, Jose,Rodriguez, Felix,Fananas, Francisco J.,Rubio, Eduardo

, p. 3084 - 3086 (2007/10/03)

The reaction of difluoroboroxy Fischer carbene complexes, vinyl ketones, and aldehydes leads to the regioselective formation of aldol-like products (see reaction scheme). The reaction also shows a high degree of diastereofacial selectivity when chiral aldehydes are used. These results show that this is a very attractive process since the regioselective formation of aldols from nearly symmetrical ketones still remains an unsolved problem.
