111291-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111291-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,2,9 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111291-55:
(8*1)+(7*1)+(6*1)+(5*2)+(4*9)+(3*1)+(2*5)+(1*5)=85
85 % 10 = 5
So 111291-55-5 is a valid CAS Registry Number.

Bicyclopropylidene: Cycloadditions onto a Unique Olefin
Meijere, A. de,Erden, Ihsan,Weber, Walter,Kaufmann, Dieter
, p. 152 - 161 (2007/10/02)
Bicyclopropylidene (1) is capable of undergoing cycloadditions in at least six different modes, depending on the nature of the cycloaddend.In analogy to its cyclodimerization, 1 adds in a and fashion to 1,3-dienes, most probably via dira
