Check Digit Verification of cas no
The CAS Registry Mumber 85655-92-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,5 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 85655-92:
(7*8)+(6*5)+(5*6)+(4*5)+(3*5)+(2*9)+(1*2)=171
171 % 10 = 1
So 85655-92-1 is a valid CAS Registry Number.

SYNTHESIS AND NUCLEOPHILIC SUBSTITUTION OF STABLE 6-HALO-PENTAFULVENES
Krimmer, Hans-Peter,Stowasser, Bernd,Hafner, Klaus
, p. 5135 - 5138 (1982)
The reaction of 2,4-di-t-butyl-cyclopentadiene-1-carbaldehyde with oxalyl chloride or oxalyl bromide provides stable 6-chloro- and 6-bromo-pentafulvenes, respectively.Several nucleophilic displacement reactions of the new compounds are described.
