51816-21-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51816-21-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,8,1 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 51816-21:
(7*5)+(6*1)+(5*8)+(4*1)+(3*6)+(2*2)+(1*1)=108
108 % 10 = 8
So 51816-21-8 is a valid CAS Registry Number.

An efficient oxidative conversion of aldehydes into 2-substituted 2-oxazolines using 1,3-diiodo-5,5-dimethylhydantoin

Takahashi, Shogo,Togo, Hideo

experimental part, p. 2329 - 2332 (2010/03/01)

Various aromatic and aliphatic aldehydes were converted into the corresponding 2-aryl and 2-alkyl-2-oxazolines, respectively, in good to high yields by reaction with 2-aminoethanol and 1,3-diiodo-5,5-dimethylhydantoin. Moreover, chiral bis-2-oxazolines, which can be used as chiral ligands in asymmetric synthesis, could be also prepared in moderate yields by the reaction of dialdehydes with (R)-(-)-2-phenylglycinol under the same conditions.

Convenient one-pot synthesis of 2-oxazolines from carboxylic acids

Hioki, Kazuhito,Takechi, Yumiko,Kimura, Noriyo,Tanaka, Hiroyuki,Kunishima, Munetaka

experimental part, p. 1735 - 1737 (2009/10/10)

Simple one-pot methods for preparation of 2-oxazolines have been developed using 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMT-MM). Treatment of a mixture of carboxylic acids and 2-haloethylammonium salts with DMT-MM in methanol
