75633-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75633-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,3 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75633-17:
(7*7)+(6*5)+(5*6)+(4*3)+(3*3)+(2*1)+(1*7)=139
139 % 10 = 9
So 75633-17-9 is a valid CAS Registry Number.

Synthesis of Simple Monocyclic 1,3-Diazepines from 1,2-Diazepines
Tsuchiya, Takashi,Kurita, Jyoji,Kojima, Hirokazu
, p. 444 - 445 (2007/10/02)
Thermolysis of the 1H-1,2-diazepines having an electron-donating substituent in the 4- or 6-position affords the corresponding 1,3-diazepines, whereas 1,2-diazepines having electron-withdrawing substituents do not show this ring-conversion.
