Check Digit Verification of cas no
The CAS Registry Mumber 65837-48-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,3 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65837-48:
(7*6)+(6*5)+(5*8)+(4*3)+(3*7)+(2*4)+(1*8)=161
161 % 10 = 1
So 65837-48-1 is a valid CAS Registry Number.

Synthesis of 1-Aryl-4-carboxymethyl-2-azetidinones
Ongania, Karl-Hans,Pawlowski, Renata
, p. 95 - 100 (2007/10/02)
The photochemically induced rearrangement of the 4-diazoacetyl-2-azetidinones 2a-d in water/acetonitrile leads exclusively to the title compounds 3a-d provided that certain reaction conditions are fulfilled.This is in contrast to the thermal, silveroxide catalysed Wolff-rearrangement of 2a in alcohols which always gives a mixture of 4, 5 and 6.The mechanism of the 1,4-ringopening of 2a to 5 and 6 is discussed. - Keywords: 1-Aryl-4-carboxymethyl-2-azetidinones, 1-Aryl-4-diazoacetyl-2-azetidinones, Diazomethane, Pentendicarboxylicacidesterhalfanilides, Wolff-Rearrangement
