41931-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41931-32-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,9,3 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 41931-32:
(7*4)+(6*1)+(5*9)+(4*3)+(3*1)+(2*3)+(1*2)=102
102 % 10 = 2
So 41931-32-2 is a valid CAS Registry Number.

Benzohydroxamic acid addition to propiolate esters - A reinvestigation
Duarte,Lobo,Prabhakar
, p. 7433 - 7435 (2007/10/03)
Addition of benzohydroxamic acid to propiolate esters gives 1,4,2-diozaxoles which originate, by base-catalysed ring opening with NaH, the isomeric O-vinyl hydroxamic acids. These compounds on thermolysis afford 1,3-oxazoles. (C) 2000 Elsevier Science Ltd.
