126502-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126502-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,0 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126502-92:
(8*1)+(7*2)+(6*6)+(5*5)+(4*0)+(3*2)+(2*9)+(1*2)=109
109 % 10 = 9
So 126502-92-9 is a valid CAS Registry Number.

Intramolecular Ring Opening Reactions of 2-Oxetanones Leading to Tetrahydrofuran Ring Formation: A Lewis Acid Study
Mead, Keith T.,Yang, Hui-Li
, p. 2991 - 2992 (1990)
A study of Lewis acid mediated intramolecular ring opening reactions of 2-oxetanones has been undertaken.Using α-substituted 4-(3-benzyloxy)propyl) analogues as substrates, we have found the reaction outcome to be highly Lewis acid dependent.
