38630-94-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38630-94-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,6,3 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 38630-94:
(7*3)+(6*8)+(5*6)+(4*3)+(3*0)+(2*9)+(1*4)=133
133 % 10 = 3
So 38630-94-3 is a valid CAS Registry Number.

Determination of regioselectivity in ring opening of tert-butylaziridinones by a combination of 15N labeling and electrospray ionization-ion trap mass spectrometry

Talaty,Van Stipdonk,Hague,Provenzano,Boese

, p. 31 - 40 (2002)

The ring opening of 1,3-di-tert-butylaziridinone by tert-butylamine and aniline was investigated by using electrospray ionization and collision-induced dissociation in an ion trap mass spectrometer in conjunction with 15N labeling of the two amine nucleophiles. Using the MSn capabilities of the ion trap instrument, we were able to monitor the retention of the 15N label through successive fragmentation steps. Both amines exhibited a remarkable degree of selectivity in that they both cleaved exclusively the 1,3-bond (the alkyl-nitrogen bond). This result is in contrast to that obtained previously with methylamine, which cleaved just the opposite bond, namely, the 1,2-bond (the acyl-nitrogen bond). These contrasting results could not have been predicted by previously published guidelines. Copyright
