Used in Pesticide Industry:
Nsc41608 is used as an intermediate for the preparation of the organochlorine pesticide Bis(2-chloroisopropyl) Ether. This pesticide is employed as a nematicide to control parasitic nematodes in agriculture, helping to protect crops from damage caused by these parasitic worms.
Check Digit Verification of cas no
The CAS Registry Mumber 6937-25-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,3 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6937-25:
(6*6)+(5*9)+(4*3)+(3*7)+(2*2)+(1*5)=123
123 % 10 = 3
So 6937-25-3 is a valid CAS Registry Number.

Cyclopropanespiro-β-lactones derived from 4-[(Z)-ethylidene]-3- methyloxetan-2-one: Diastereoselective formation and rearrangement reactions
Geraghty, Niall W.A.,McArdle, Patrick,Mullen, Laverne M.A.
experimental part, p. 3546 - 3552 (2011/06/11)
The metal catalysed reaction of monosubstituted diazo esters and ketones with 4-[(Z)-ethylidene]-3-methyloxetan-2-one results in the formation of cyclopropanespiro-β-lactones. In contrast to most alkene cyclopropanations, including those involving diketene, the reaction occurs diastereoselectively. A computational model of the reaction has been developed that accounts for the observed stereochemistry. The metal promoted thermal rearrangement of these spiro compounds is also unusual in that it affords pyranones, rather than the decarboxylation products characteristic of β-lactones in general, or the furanones formed from diketene derived cyclopropanespiro-β-lactones.
