Check Digit Verification of cas no

The CAS Registry Mumber 1029604-58-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,9,6,0 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1029604-58:
(9*1)+(8*0)+(7*2)+(6*9)+(5*6)+(4*0)+(3*4)+(2*5)+(1*8)=137
137 % 10 = 7
So 1029604-58-7 is a valid CAS Registry Number.

Asymmetric petasis reactions catalyzed by chiral biphenols

Lou, Sha,Schaus, Scott E.

, p. 6922 - 6923 (2008/09/21)

Chiral biphenols catalyze the enantioselective Petasis reaction of alkenyl boronates, secondary amines, and ethyl glyoxylate. The reaction requires the use of 15 mol % of (S)-VAPOL as the catalyst, alkenyl boronates as nucleophiles, ethyl glyoxylate as the aldehyde component, and 3 A molecular sieves as an additive. The chiral α-amino ester products are obtained in good yields (71-92%) and high enantiomeric ratios (89:11-98:2). Mechanistic investigations indicate single ligand exchange of acyclic boronate with VAPOL and tetracoordinate boronate intermediates. Copyright
