Check Digit Verification of cas no

The CAS Registry Mumber 280128-43-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,0,1,2 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 280128-43:
(8*2)+(7*8)+(6*0)+(5*1)+(4*2)+(3*8)+(2*4)+(1*3)=120
120 % 10 = 0
So 280128-43-0 is a valid CAS Registry Number.

Sulfenate substitution as a complement and alternative to sulfoxidation in the diastereoselective preparation of chiral β-substituted β-amino sulfoxides

S?derman, Stefan C.,Schwan, Adrian L.

, p. 1638 - 1649 (2013/03/28)

Building from a previous communication, the reaction of sulfenate anions with chiral N-Boc-protected β-substituted β-amino iodides was evaluated as a conceptually different synthetic approach to chiral β-substituted β-amino sulfoxides. Using arenesulfenat

Additions of Enantiopure α-Sulfinyl Carbanions to (S)-N-Sulfinimines: Asymmetric Synthesis of β-Amino Sulfoxides and β-Amino Alcohols

Garcia Ruano, Jose L.,Alcudia, Ana,Del Prado, Miriam,Barros, David,Carmen Maestro,Fernandez, Inmaculada

, p. 2856 - 2862 (2007/10/03)

The addition of the lithium anions derived from (R)- and (S)-methyl and -ethyl p-tolyl sulfoxides to (S)-N-benzylidene-p-toluenesulfinamide provides an easy access route to enantiomerically pure β-(N-sulfinyl)amino sulfoxides. Stereoselectivity can be ach
