Check Digit Verification of cas no
The CAS Registry Mumber 417725-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,7,7,2 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 417725-91:
(8*4)+(7*1)+(6*7)+(5*7)+(4*2)+(3*5)+(2*9)+(1*1)=158
158 % 10 = 8
So 417725-91-8 is a valid CAS Registry Number.

A chiral titanium complex, Ti(O-i-Pr)4/BINOL/tert-butylcatechol, catalyzes enantioselective addition reaction of ketene silyl acetals to nitrones to give optically active β-amino acid derivatives which are biologically active compounds and useful synthetic intermediates of natural products and pharmaceuticals such as β-lactam antibiotics. The combined process of catalytic oxidation of secondary amines and enantioselective carbon-carbon bond formation of nitrones thus obtained with ketene silyl acetals provides a useful two-step method for the synthesis of optically active β-amino acid derivatives and related nitrogen compounds.
