The CAS Registry Mumber 1429332-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,9,3,3 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1429332-52:
(9*1)+(8*4)+(7*2)+(6*9)+(5*3)+(4*3)+(3*2)+(2*5)+(1*2)=154
154 % 10 = 4
So 1429332-52-4 is a valid CAS Registry Number.

Synthesis of 3-arylcoumarins through N-heterocyclic carbene catalyzed condensation and annulation of 2-chloro-2-arylacetaldehydes with salicylaldehydes

Jiang, Yuansong,Chen, Wanzhi,Lu, Weimin

, p. 3669 - 3676 (2013/05/08)

The condensation reaction of 2-chloro-2-arylacetaldehyde with salicylaldehyde catalyzed by N-heterocyclic carbene (NHC) leading to 3-arylcoumarin was studied. A number of 3-arylcoumarin derivatives were obtained in good to excellent yields via this umpolung reaction. This reaction is facile and experimentally simple and mild.
