132431-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132431-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,3 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132431-56:
(8*1)+(7*3)+(6*2)+(5*4)+(4*3)+(3*1)+(2*5)+(1*6)=92
92 % 10 = 2
So 132431-56-2 is a valid CAS Registry Number.

Generation of 2,3-naphthoquinones under non-oxidative conditions
Jones, David W.,Nongrum, Matthew
, p. 3357 - 3358 (2007/10/02)
The 2,3-naphthoquinones 1 (R = Ph, o-tolyl, COPh, Cl and Prn) can be generated by desilylation-debromination induced by fluoride ion (4; arrows) and trapped as the adducts 5 with norbornadiene.
