77357-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77357-55-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,5 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77357-55:
(7*7)+(6*7)+(5*3)+(4*5)+(3*7)+(2*5)+(1*5)=162
162 % 10 = 2
So 77357-55-2 is a valid CAS Registry Number.

, p. 2745 - 2752 (2007/10/02)
New routes to 2-methoxy-3-methyl-1,4-benzoquinone and 4-methoxy-3-methyl-1,2-benzoquinone have been developed.Both quinones undergo highly regioselective oxidative amination with pyrrolidine and copper acetate, yielding aminoquinones related to the mitomy
