1350520-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1350520-43-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,0,5,2 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1350520-43:
(9*1)+(8*3)+(7*5)+(6*0)+(5*5)+(4*2)+(3*0)+(2*4)+(1*3)=112
112 % 10 = 2
So 1350520-43-2 is a valid CAS Registry Number.

A ring fragmentation approach to medium-sized cyclic 2-alkynones
Tsvetkov, Nikolay P.,Bayir, Ali,Schneider, Samuel,Brewer, Matthias
, p. 264 - 267 (2012/02/15)
Bicyclic γ-silyloxy-β-hydroxy-α-diazoketones, in which the Cβ-Cγ bond is the ring fusion bond, productively fragment when treated with tin(IV) chloride to provide medium-sized cyclic 2-alkynones. This method provides good to excellent yields of 10-, 11-,
