134589-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134589-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,8 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134589-71:
(8*1)+(7*3)+(6*4)+(5*5)+(4*8)+(3*9)+(2*7)+(1*1)=152
152 % 10 = 2
So 134589-71-2 is a valid CAS Registry Number.

A convenient palladium-catalyzed synthesis of alkynyl substituted Schiff's bases by coupling of imidoyl chlorides with 1-alkynes
Lin,Sheng,Huang
, p. 235 - 236 (2007/10/02)
Alkyne substituted Schiff's bases 3 for example N-(1-phenyl-2-hexynylidene)aniline (3e), were conveniently synthesized from imidoyl chlorides 1 and 1-alkynes 2 in the presence of a palladium catalyst.
