132453-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132453-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,5 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132453-91:
(8*1)+(7*3)+(6*2)+(5*4)+(4*5)+(3*3)+(2*9)+(1*1)=109
109 % 10 = 9
So 132453-91-9 is a valid CAS Registry Number.

A radical cyclisation reaction based strategy to 2,3,5-tri- and tetrasubstituted furans
Srikrishna,Sundarababu
, p. 7901 - 7910 (2007/10/02)
Synthesis of 2,3,5-trisubstituted furans (5), starting from 2-methoxypropene and 1,3-disubstituted propargyl alcohols 3, via the radical cyclisation of the bromo acetal 4 followed by aromatisation, is reported. Analogously, 1-methoxycyclohexene and propar
