167708-84-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 167708-84-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,7,0 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 167708-84:
(8*1)+(7*6)+(6*7)+(5*7)+(4*0)+(3*8)+(2*8)+(1*4)=171
171 % 10 = 1
So 167708-84-1 is a valid CAS Registry Number.

An Efficient Straightforward Synthesis of Benzazulene
Sperandio, David,Hansen, Hans-Juergen
, p. 765 - 771 (2007/10/02)
Benzazulene (1) is synthesized in five steps (cf.Scheme 2) starting from commercially available 2-iodobenzyl alcohol (4) and tropylium tetrafluoroborate in an overall yield of 44percent.The key step (cf. also Scheme 1) is the intramolecular Heck reacti
