Check Digit Verification of cas no

The CAS Registry Mumber 1233693-21-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,6,9 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1233693-21:
(9*1)+(8*2)+(7*3)+(6*3)+(5*6)+(4*9)+(3*3)+(2*2)+(1*1)=144
144 % 10 = 4
So 1233693-21-4 is a valid CAS Registry Number.

Pd-catalyzed reaction of sterically hindered hydrazones with aryl halides: Synthesis of tetra-substituted olefins related to iso-combretastatin A4

Brachet, Etienne,Hamze, Abdallah,Peyrat, Jean-Francois,Brion, Jean-Daniel,Alami, Mouad

scheme or table, p. 4042 - 4045 (2010/11/16)

PdCl2(MeCN)2 in combination with dppp proved to be a powerful and efficient catalyst for the coupling of sterically hindered N-arylsulfonylhydrazones with aryl halides, thus providing a flexible and convergent access to tetrasubstituted olefins related to iso-combretastatin A4 in good yields. This new protocol has been applied successfully to the formal synthesis of biphenylisopropylidene 4-pyridine CYP17 inhibitor, 12b, of biological interest.
