Check Digit Verification of cas no

The CAS Registry Mumber 678554-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,5,5 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 678554-43:
(8*6)+(7*7)+(6*8)+(5*5)+(4*5)+(3*4)+(2*4)+(1*3)=213
213 % 10 = 3
So 678554-43-3 is a valid CAS Registry Number.

Palladium-catalyzed coupling of N-tosylhydrazones and β-bromostyrene derivatives: New approach to 2H-chromenes

Xia, Yamu,Xia, Ying,Zhang, Yan,Wang, Jianbo

supporting information, p. 9333 - 9336 (2014/12/11)

2H-Chromene is an important structural motif that exists in natural products and non-natural compounds possessing interesting biological activities. In this investigation, a highly efficient approach toward 2H-chromenes has been developed based on palladium-catalyzed coupling of N-tosylhydrazones and β-bromostyrenes. The mechanism of this reaction is proposed that involves the formation of vinyl palladium by carbene migratory insertion and the intramolecular nucleophilic substitution. This journal is
