Check Digit Verification of cas no

The CAS Registry Mumber 1323883-35-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,3,8,8 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1323883-35:
(9*1)+(8*3)+(7*2)+(6*3)+(5*8)+(4*8)+(3*3)+(2*3)+(1*5)=157
157 % 10 = 7
So 1323883-35-7 is a valid CAS Registry Number.

Kinetics and mechanism of the aminolysis of aryl N-benzyl thiocarbamates in acetonitrile

Oh, Hyuck Keun

, p. 137 - 140 (2011/11/01)

The aminolysis reactions of phenyl N-benzyl thiocarbamate with benzylamines in acetonitrile at 50.0 °C are investigated. The reactions are first order in both the amine and the substrate. Under amine excess, pseudo-first coefficient (kobs) are obtained, plot of kobs vs free amine concentration are linear. The signs of ρXZ (X and ρZ with respect to the sustituent in the substrate and large ρXZ value indicate that the reactions proceed concerted mechanism. The normal kinetic isotope effects (kH/k D = 1.3 ~ 1.5) involving deuterated benzylamine nucleophiles suggest a hydrogen-bonded, four-centered-type transition state. The activation parameters, ΔH?and AS?, are consistent with this transition state structure.
