Check Digit Verification of cas no
The CAS Registry Mumber 21210-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,1 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21210-43:
(7*2)+(6*1)+(5*2)+(4*1)+(3*0)+(2*4)+(1*3)=45
45 % 10 = 5
So 21210-43-5 is a valid CAS Registry Number.

Catalytic enantioselective O-H insertion reactions
Maier, Thomas C.,Fu, Gregory C.
, p. 4594 - 4595 (2006)
The first effective method for catalytic enantioselective insertions into O-H bonds has been developed. Specifically, a copper/bisazaferrocene catalyst couples alcohols such as 2-trimethylsilylethanol with α-aryl-α-diazo esters in high yield and good ee.
A Unified Strategy for the Asymmetric Synthesis of Highly Substituted 1,2-Amino Alcohols Leading to Highly Substituted Bisoxazoline Ligands

A general procedure for the asymmetric synthesis of highly substituted 1,2-amino alcohols in high yield and diastereoselectivity is described that uses organometallic additions of a wide range of nucleophiles to tert-butylsulfinimines as the key step. The addition of organolithium reagents to these imines follows a modified Davis model. The diastereoselectivity for this reaction depends significantly on both the nucleophile and electrophile. These highly substituted 1,2-amino alcohols are used to synthesize stereochemically diverse and structurally novel, polysubstituted 2,2′-methylene(bisoxazoline) ligands in high yields.
