Check Digit Verification of cas no

The CAS Registry Mumber 132734-00-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,3 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 132734-00:
(8*1)+(7*3)+(6*2)+(5*7)+(4*3)+(3*4)+(2*0)+(1*0)=100
100 % 10 = 0
So 132734-00-0 is a valid CAS Registry Number.

Novel Transannular Reactions in the Acid Hydrolysis of Diazotized syn- and anti-4-Amino(1,4)naphthalenoparacyclophanes

Takada, Yoshihiro,Tsuchiya, Kazuhiko,Takahashi, Senji,Mori, Nobuo

, p. 2141 - 2145 (2007/10/02)

The diazonium ions derived from the title syn- and anti-4-aminocyclophanes 1a und 4a in aqueous solution undergo transannular reactions to give 17-hydroxy(1,4)naphthalenoparacyclophane 3a and 9,10-dihydro-1,9:4,10-diethano-9,10-ethenoanthracene 6a, respectively.Deuterium-tracer experiments suggest that the reaction of diazotized 1a proceeds via a pathway involving tranannular diazo coupling followed by generation of a 16,17-didehydro intermediate.On the other hand, the reaction pathway of diazotized 4a involves dediazonization followed by transannular electrophilic addition.
