142188-16-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142188-16-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,8 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142188-16:
(8*1)+(7*4)+(6*2)+(5*1)+(4*8)+(3*8)+(2*1)+(1*6)=117
117 % 10 = 7
So 142188-16-7 is a valid CAS Registry Number.

Trapping Reactions of 1,3-Bridged Cyclopropenes

Halton, Brian,Diggins, Mathew D.,Kay, Andrew J.

, p. 4080 - 4083 (1992)

The reactive bicycloalk-1(ω)-enes (n = 3-6) 9a-d are formed by dehydrochlorination of 8a-d and trapped by diphenylisobenzofuran as exo Diels-Alder adducts 10a-d.With 8c the major adduct, 18 results not from interception of 9c but from diene 16 that is formed by dehydrochlorination/rearrangement sequences.Attempted interception of cylopropenes 9a-d by furan provides a product 19 from 9b (n = 4) only.Under the conditions employed, 9a (n = 3) ring expands to carbene prior to furan trapping while homologues 9c and 9d ( n > 4) rearrange and lose HCl too give 17 and 20, respectively, without intervention of furan. 7-Chlorobicyclohepta-1(7),3-diene is likewise captured by diphenylisobenzofuran as 13.
