33974-40-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33974-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,7 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33974-40:
(7*3)+(6*3)+(5*9)+(4*7)+(3*4)+(2*4)+(1*0)=132
132 % 10 = 2
So 33974-40-2 is a valid CAS Registry Number.

Photooxygenation of masked o-benzoquinones: An efficient entry into highly functionalized cyclopentenones from 2-methoxyphenols

Kao, Tzu-Chiao,Chuang, Gary Jing,Liao, Chun-Chen

supporting information; experimental part, p. 7325 - 7327 (2009/04/10)

(Chemical Equation Presented) MOB tactics: A novel oxidation of masked o-benzoquinones (MOBs) 1 occurs by singlet-oxygen-triggered ring contraction to form cyclopentenone derivatives 2 and by [4+2] cycloaddition to give endoperoxides 3. The competing path

1,3-Methoxy rearrangement of masked o-benzoquinones: A novel synthesis of p-quinol ethers

Yang, Ching-Shun,Liao, Chun-Chen

, p. 4809 - 4812 (2008/03/15)

(Chemical Equation Presented) p-Quinol ethers are valuable synthons in synthetic organic chemistry. MOBs 1a-1l can be converted to p-quinol ethers 2a-2i in a highly efficient manner via 1,3-methoxy migration catalyzed by Lewis acids. The migration was fou
