Check Digit Verification of cas no
The CAS Registry Mumber 50491-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,4,9 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50491-29:
(7*5)+(6*0)+(5*4)+(4*9)+(3*1)+(2*2)+(1*9)=107
107 % 10 = 7
So 50491-29-7 is a valid CAS Registry Number.

REACTIONS OF DIMETHYL 2-METHOXYISOXAZOLIDINE-3,3-DICARBOXYLATE CATALYZED BY LEWIS ACIDS
Rudchenko, V. F.,Voznesenskii, V. N.,Kostyanovskii, R. G.
, p. 96 - 102 (2007/10/02)
Evidence is presented for a synchronous mechanism of the acid-catalyzed 1,2-rearrangement of 2-methoxyisoxazolidine-2,3-dicarboxylic acid ester with migration of the ester group to the N-atom.It was shown that the reaction is suppressed in the presence of an external nucleophile or a reducing agent.The regularities found were used to explain the transformations of bicyclic systems with an -ONO-fragment.
