23919-71-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23919-71-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 23919-71:
(7*2)+(6*3)+(5*9)+(4*1)+(3*9)+(2*7)+(1*1)=123
123 % 10 = 3
So 23919-71-3 is a valid CAS Registry Number.

Nyerges,Fejes,Virányi,Groundwater,T?ke
, p. 1479 - 1482 (2007/10/03)
An efficient two-step synthesis of 1-aryl-2-dimethylamnoethanols 4 is described, consisting of oxazolidine 3 generation from the cycloaddition of an azomethine ylide to an aldehyde, followed by reductive ring-opening.
