144582-97-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144582-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,5,8 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 144582-97:
(8*1)+(7*4)+(6*4)+(5*5)+(4*8)+(3*2)+(2*9)+(1*7)=148
148 % 10 = 8
So 144582-97-8 is a valid CAS Registry Number.

Synthesis of pyridazo[3,4-e][1.4]diazepines by 'inverse' intramolecular Diels-Alder reaction
Yang,Seitz
, p. 563 - 564 (2007/10/02)
Intramolecular [4+2] cycloaddition reactions with inverse electron demand of differently substituted tetrazines 3a-c, carrying 7-membered ω-alkyne side-chain dienophiles lead to the synthesis of novel pyridazo[3,4-e][1.4]diazepines 5-7.
