1161880-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1161880-50-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,1,8,8 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1161880-50:
(9*1)+(8*1)+(7*6)+(6*1)+(5*8)+(4*8)+(3*0)+(2*5)+(1*0)=147
147 % 10 = 7
So 1161880-50-7 is a valid CAS Registry Number.

Studies toward intramolecular cycloaddition of o-quinodimethane with an oxazole moiety
Matsuya, Yuji,Qin, Hongbo,Nemoto, Hideo
, p. 773 - 779 (2009)
Thermal reaction of benzocyclobutene derivatives having an oxazole moiety was investigated. Intramolecular [4+2] cycloaddition of o-quinodimethane, generated by thermolysis of the benzocyclobutene, with the oxazole did not proceed, and instead, [1,5]-sigm
