291273-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 291273-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,2,7 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 291273-71:
(8*2)+(7*9)+(6*1)+(5*2)+(4*7)+(3*3)+(2*7)+(1*1)=147
147 % 10 = 7
So 291273-71-7 is a valid CAS Registry Number.

The reversible nature of the imine bond formation in CDCl(3) solution has been exploited to exchange substituted for unsubstituted m-phenylenediamine (MPD) units in hemicarcerand octaimines. Moreover, acid-catalyzed imine exchange has been shown to provid
