Check Digit Verification of cas no

The CAS Registry Mumber 927681-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,7,6,8 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 927681-77:
(8*9)+(7*2)+(6*7)+(5*6)+(4*8)+(3*1)+(2*7)+(1*7)=214
214 % 10 = 4
So 927681-77-4 is a valid CAS Registry Number.

An aza-Michael addition protocol to fluoroalkylated β-amino acid derivatives and enantiopure trifluoromethylated N-heterocycles

Yang, Xing,Chen, Zhuo,Cai, Yuan,Huang, Yi-Yong,Shibata, Norio

, p. 4530 - 4534 (2014)

The aza-Michael reaction with β-fluoroalkylated acrylates provided the corresponding fluoroalkylated β-amino acid derivatives in up to 99% yield under catalyst- and solvent-free conditions. An enantioenriched β-trifluoromethylated β-amino acid was obtained in good yield through a scale-up diastereoselective aza-Michael addition, which facilitated the installation of enantiopure trifluoromethylated analogues of β-lactam and dihydroquinolin-4-one.

Practical, highly enantioselective chemoenzymatic one-pot synthesis of short-chain aliphatic β-amino acid esters

Wei?, Markus,Gr?ger, Harald

experimental part, p. 1251 - 1254 (2009/09/06)

A practical, highly enantioselective method for the synthesis of short-chain aliphatic β-amino acid esters was developed starting from prochiral and easily accessible substrates. This chemoenzymatic approach is based on a nonenzymatic aza-Michael addition
