452056-00-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 452056-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,0,5 and 6 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 452056-00:
(8*4)+(7*5)+(6*2)+(5*0)+(4*5)+(3*6)+(2*0)+(1*0)=117
117 % 10 = 7
So 452056-00-7 is a valid CAS Registry Number.

Synthesis of substituted naphthalenes by the palladium-catalyzed annulation of internal alkynes
Huang, Qinhua,Larock, Richard C.
, p. 2505 - 2508 (2002)
(Matrix presented) A variety of substituted naphthalenes have been prepared by the palladium-catalyzed carboannulation of internal alkynes. This method (1) forms two new carbon-carbon bonds in a single step, (2) accommodates a variety of functional groups
