128413-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128413-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,1 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128413-22:
(8*1)+(7*2)+(6*8)+(5*4)+(4*1)+(3*3)+(2*2)+(1*2)=109
109 % 10 = 9
So 128413-22-9 is a valid CAS Registry Number.

Spiroheterocycles from Reaction of Nitrile Oxides with 3-Methylenephthalimidines
Howe, Robert K.,Shelton, Becky R.
, p. 4603 - 4607 (2007/10/02)
In explorations of syntheses and chemistry of spiroheterocycles, we found that reaction of aromatic nitrile oxides with 3-methylenephthalimidines 8 produced spiroheterocycles 9.When N-benzyl-3-methylenephthalimidine (8c) was employed, oximes 10 and 11 wer
