135249-37-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135249-37-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,4 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 135249-37:
(8*1)+(7*3)+(6*5)+(5*2)+(4*4)+(3*9)+(2*3)+(1*7)=125
125 % 10 = 5
So 135249-37-5 is a valid CAS Registry Number.

BENZYLATION OF 1-BENZYLIDENE-3-PYRAZOLIDINIUM OXIDES
Dowling, James E.,Anselme, J.-P.
, p. 359 - 360 (2007/10/02)
The benzylation of 1-benzylidene-5-phenyl-3-pyrazolidinium oxide (2a) gives five products including the "head to head" dimer of 2 (7) and the ring-opened 1-benzyl-1-cinnamoylhydrazone (4a).Similar behavior was also observed with ylides bearing various sub
