135673-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135673-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,7 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135673-95:
(8*1)+(7*3)+(6*5)+(5*6)+(4*7)+(3*3)+(2*9)+(1*5)=149
149 % 10 = 9
So 135673-95-9 is a valid CAS Registry Number.

The reaction of benzoyl substituted heterocyclic ketene aminals with 4-nitrobenzhydroximic acid chloride
Huang,Wang
, p. 1167 - 1176 (2007/10/02)
Heterocyclic ketene aminals 1 or 2 reacted with 4-nitrobenzhydroximic acid chloride (3) to give the 3,5-diaryl-4-(2-imidazolinyl)-isoxazoles 4 or 3,5-diaryl-4-(2-tetrahydropyrimidinyl)-isoxazoles 5. The mechanism of their formation were also discussed.
