413621-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 413621-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,3,6,2 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 413621-19:
(8*4)+(7*1)+(6*3)+(5*6)+(4*2)+(3*1)+(2*1)+(1*9)=109
109 % 10 = 9
So 413621-19-9 is a valid CAS Registry Number.

Asymmetric synthesis of 3-aryl-substituted 2,3-dihydro-1H-isoindol-1-ones
Enders, Dieter,Braig, Volker,Raabe, Gerhard
, p. 1528 - 1535 (2007/10/03)
The first asymmetric synthesis of 3-aryl substituted 2,3-dihydro-1H-isoindol-1-ones via a tandem nucleophilic 1,2-addition ring closure procedure from SAMP and (or) RAMP hydrazones and subsequent oxidative cleavage of the auxiliary is reported.
