135482-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135482-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,4,8 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135482-21:
(8*1)+(7*3)+(6*5)+(5*4)+(4*8)+(3*2)+(2*2)+(1*1)=122
122 % 10 = 2
So 135482-21-2 is a valid CAS Registry Number.

Annelation Reactions of 4-Alkynylcyclobutenones. Formation of Methylenebenzofurans
Xu, Simon L.,Taing, Meng,Moore, Harold W.
, p. 6104 - 6109 (2007/10/02)
Thermolysis of a number of 4-alkynyl-4-(propargyloxy)cyclobutenones is reported.These studies show a remarkable rearrangement to methylenebenzofurans accompanied by remote alkene formation.The mechanism and scope of the reactions are descussed.
