Check Digit Verification of cas no

The CAS Registry Mumber 1452841-05-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,2,8,4 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1452841-05:
(9*1)+(8*4)+(7*5)+(6*2)+(5*8)+(4*4)+(3*1)+(2*0)+(1*5)=152
152 % 10 = 2
So 1452841-05-2 is a valid CAS Registry Number.

Asymmetric organocatalytic 1,4-addition reactions starting from enals with gem-difluoroalkyl side chains

Khalaf, Ali,Gree, Danielle,Abdallah, Hassan,Jaber, Nada,Hachem, Ali,Gree, Rene

, p. 653 - 657 (2013)

gem-Difluoroenals are excellent substrates for asymmetric organocatalytic 1,4-additions of thiols and anilines. By using diarylsilylprolinol ether as a catalyst, good to excellent yields with ee values in the same range (up to 98 %) were obtained. The CF2R group strongly activates the enals towards these organocatalytic additions. New chiral β-thio and β-amino aldehydes with CF2R chains can be obtained in high yields with high ee values by asymmetric organocatalytic processes after selection of the appropriate catalyst and optimization of the reaction conditions.
