137063-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137063-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,6 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137063-63:
(8*1)+(7*3)+(6*7)+(5*0)+(4*6)+(3*3)+(2*6)+(1*3)=119
119 % 10 = 9
So 137063-63-9 is a valid CAS Registry Number.

The reaction of benzoyl substituted heterocyclic ketene animals with 2, 4, 6,-trimethylbenzonitrile oxide
Huang,Wang
, p. 1909 - 1915 (2007/10/02)
Heterocyclic ketene animals 1 or 2 reacted with 2, 4, 6-trimethylbenzonitrile oxide (3) to afford the 3,5-diaryl-4-(2-imidazolinyl)-isoxazoles 4 or 3,5-diaryl-4-(2-tetrahydropyrimidinyl)-isoxazoles 5. The mechanism of their formation was discussed.
