134541-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134541-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,4 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134541-97:
(8*1)+(7*3)+(6*4)+(5*5)+(4*4)+(3*1)+(2*9)+(1*7)=122
122 % 10 = 2
So 134541-97-2 is a valid CAS Registry Number.

Ethano- and Etheno-bridged 2-Pyridyl Isoxazoles and Thiazoles, and Their Reduced Variants

, p. 765 - 770 (2007/10/02)
(E)-2-(2-Oxobut-3-enyl)pyridine 21, (E)-2-(but-1-en-3-ynyl)pyridine 7 and (E)-2-(buta-1,3-dienyl)pyridine 15 are precursors for 2-pyridyl etheno-bridged isoxazoles and thiazoles, and a range of specifically reduced variants.
