134304-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134304-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,3,0 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134304-39:
(8*1)+(7*3)+(6*4)+(5*3)+(4*0)+(3*4)+(2*3)+(1*9)=95
95 % 10 = 5
So 134304-39-5 is a valid CAS Registry Number.

INTRAMOLECULAR RADICAL CYCLIZATION OF PHENOLIC NITRONATES: FACILE SYNTHESIS OF ANNELATED TROPONE AND TROPOLONE DERIVATIVES
Kende, Andrew S.,Koch, Kevin
, p. 6051 - 6054 (2007/10/02)
Treatment of the phenolic nitroalkanes 1 in dilute base with K3Fe(CN)6 results in the formation of spirocyclic nitro dienones 3 which undergo facile rearrangement to annelated tropone or tropolone derivatives.
