Check Digit Verification of cas no
The CAS Registry Mumber 832-83-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 832-83:
(5*8)+(4*3)+(3*2)+(2*8)+(1*3)=77
77 % 10 = 7
So 832-83-7 is a valid CAS Registry Number.

Squaramide-catalyzed asymmetric Mannich reactions between 3-fluorooxindoles and pyrazolinone ketimines

An enantioselective Mannich reaction between 3-fluorooxindoles and pyrazolinone ketimines has been developed for the construction of amino-pyrazolone-oxindoles containing stereogenic C-F units. Based on this new protocol that allows for the generation of two adjacent tetrasubstituted stereocenters, a variety of structurally diverse fluorinated amino-pyrazolone-oxindoles were obtained in good to excellent yields with excellent diastereoselectivities and enantioselectivities (up to 98% yield, >20:1 dr and >99% ee). What's more, good yield and high stereoselectivities were obtained in the gram-scale reaction.
