143723-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143723-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,2 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143723-23:
(8*1)+(7*4)+(6*3)+(5*7)+(4*2)+(3*3)+(2*2)+(1*3)=113
113 % 10 = 3
So 143723-23-3 is a valid CAS Registry Number.

Asymmetric synthesis with chiral hydrogenolysable amines, ω-imino esters reduction: A diastereoselective route to ω-alkyl lactams
Marx,El Bouz,Celerier,Lhommet
, p. 4307 - 4310 (2007/10/02)
Chiral methylbenzylamine is used to prepare ω-amino esters which are then transformed into ω-alkyl lactams with good diastereoselectivity.
