Check Digit Verification of cas no

The CAS Registry Mumber 123433-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,3 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123433-58:
(8*1)+(7*2)+(6*3)+(5*4)+(4*3)+(3*3)+(2*5)+(1*8)=99
99 % 10 = 9
So 123433-58-9 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 (2007/10/02)

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.

SYSTHESIS AND INTRAMOLECULAR RING CLEAVAGE OF 2-OXETANONES

Mead, Keith T.,Samuel, Beverly

, p. 6573 - 6576 (2007/10/02)

Intermolecular 2+2 aldehyde-ketene cycloaddition, followed by Lewis acid induced intramolecular ring opening of the 2-oxetanone product have been used to prepare tetrahydrofuran and tetrahydropyran ring systems.
