Check Digit Verification of cas no

The CAS Registry Mumber 229156-24-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,1,5 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 229156-24:
(8*2)+(7*2)+(6*9)+(5*1)+(4*5)+(3*6)+(2*2)+(1*4)=135
135 % 10 = 5
So 229156-24-5 is a valid CAS Registry Number.

Synthesis of non-racemic nitrogen-containing diselenides as efficient precursor catalysts in the diethylzinc addition to benzaldehyde

Santi, Claudio,Wirth, Thomas

, p. 1019 - 1023 (2007/10/03)

Short synthetic procedures for the preparation of new chiral, non- racemic nitrogen-containing diselenides are described. Only 1 mol% of these diselenides can very efficiently catalyze the diethylzinc addition to benzaldehydes affording the secondary alcohols in high enantiomeric purities (up to 97% ee).
