Check Digit Verification of cas no

The CAS Registry Mumber 927411-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,7,4,1 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 927411-34:
(8*9)+(7*2)+(6*7)+(5*4)+(4*1)+(3*1)+(2*3)+(1*4)=165
165 % 10 = 5
So 927411-34-5 is a valid CAS Registry Number.

Enantioselective addition of phenylacetylene to aldehydes catalyzed by polymer-supported titanium(IV) complexes of β-hydroxy amides

Hui, Xin-Ping,Huang, Lu-Ning,Li, Ya-Min,Wang, Ren-Lin,Xu, Peng-Fei

experimental part, p. 347 - 354 (2010/11/19)

A series of polymer-supported chiral β-hydroxy amides and C 2-symmetric β-hydroxy amides have been synthesized and successfully used for the enantioselective addition of phenylacetylene to aldehydes. High yields (up to 93%) and enantioselectivities (up to 92% ee) were achieved by using polymer-supported chiral bhydroxy amide 4b. The resin 4b is reused four times, giving the product with enantioselectivity 80% ee. Fortunately, it is found that this heterogonous system is suitable not only for aromatic aldehydes but also aliphatic aldehyde.
