28785-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28785-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,8 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28785-74:
(7*2)+(6*8)+(5*7)+(4*8)+(3*5)+(2*7)+(1*4)=162
162 % 10 = 2
So 28785-74-2 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.
