Check Digit Verification of cas no

The CAS Registry Mumber 953393-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,3,3,9 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 953393-41:
(8*9)+(7*5)+(6*3)+(5*3)+(4*9)+(3*3)+(2*4)+(1*1)=194
194 % 10 = 4
So 953393-41-4 is a valid CAS Registry Number.

A turn-on fluorescent indicator for citrate with micromolar sensitivity

Burguete, M. Isabel,Galindo, Francisco,Luis, Santiago V.,Vigara, Laura

, p. 4027 - 4033 (2007)

A turn-on fluorescent indicator for citric acid (citrate) has been developed, displaying high emission enhancement (+1500%) and low interference by other carboxylates. The sensor is based on the non-emissive copper(ii) complex of a fluorescent amino amide, which, upon addition of citrate decomplexates to yield the emissive ligand. The detection limit estimated for this new chemosensing system is about 0.5 M. This novel approach to the analysis of citrate constitutes an alternative ca. 102-103 times more sensitive than the standard method based on the enzyme citrate lyase. The Royal Society of Chemistry.

Nickel complexes from α-amino amides as efficient catalysts for the enantioselective Et2Zn addition to benzaldehyde

Burguete, M. Isabel,Collado, Manuel,Escorihuela, Jorge,Galindo, Francisco,García-Verdugo, Eduardo,Luis, Santiago V.,Vicent, María J.

, p. 6891 - 6894 (2007/10/03)

Ni2+ complexes derived from simple α-amino amides catalyze very efficiently the addition of Et2Zn to benzaldehyde, giving (S)-1-phenylethanol as the major isomer in most cases (94% yield, 97% ee for R=Bn). The nature of the substituent on the amide nitrogen atom seems to play a key role in determining the asymmetric induction observed.
