Check Digit Verification of cas no

The CAS Registry Mumber 221550-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,5,5 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 221550-49:
(8*2)+(7*2)+(6*1)+(5*5)+(4*5)+(3*0)+(2*4)+(1*9)=98
98 % 10 = 8
So 221550-49-8 is a valid CAS Registry Number.

Synthesis of chiral organocatalysts derived from aziridines: Application in asymmetric aldol reaction

Gandhi, Shikha,Singh, Vinod K.

scheme or table, p. 9411 - 9416 (2009/04/06)

(Chemical Equation Presented) We report the synthesis of a new series of highly efficient chiral organocatalysts derived via the regio-and stereoselective ring opening of chiral aziridines with azide anions. The catalysts have proved to be very efficient

Catalytic enantioselective reactions. Part 12. Enantioselective addition of diethylzinc to aldehydes catalyzed by zinc complexes modified with chiral β-sulfonamidoalcohols

Cho, Byung Tae,Chun, Yu Sung

, p. 521 - 531 (2007/10/03)

Various new chiral β-sulfonamidoalcohols were prepared. The zinc complexes modified by these chiral ligands alone without the use of titanium tetraisopropoxide are effective as chiral catalysts for the addition of diethylzinc to aldehydes to afford second
