Check Digit Verification of cas no
The CAS Registry Mumber 10138-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,3 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 10138-89:
(7*1)+(6*0)+(5*1)+(4*3)+(3*8)+(2*8)+(1*9)=73
73 % 10 = 3
So 10138-89-3 is a valid CAS Registry Number.

Direct C-4 arylation of crotonaldehyde with arenediazonium tetrafluoroborates
Zaragoza, Florencio,Heinze, Verena
scheme or table, p. 4678 - 4680 (2011/09/20)
Arenediazonium tetrafluoroborates react with crotonaldehyde (2-butenal) in methanol in the presence of catalytic amounts of Pd(OAc)2 to yield mainly 4,4-dimethoxy-1-butenylarenes. In most of the examples studied, small amounts of an isomeric byproduct were formed, presumably 3,3-dimethoxy-1- methylenepropylarenes. Because crotonaldehyde and arenediazonium salts are cheap and readily available, this reaction is a convenient access to protected 4-arylbutenals.
