47861-54-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 47861-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,7,8,6 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 47861-54:
(7*4)+(6*7)+(5*8)+(4*6)+(3*1)+(2*5)+(1*4)=151
151 % 10 = 1
So 47861-54-1 is a valid CAS Registry Number.

[5]Helicenes by tandem radical cyclisation
Harrowven, David C.,Nunn, Michael I.T.,Fenwick, David R.
, p. 7345 - 7347 (2002)
A new and rapid approach to [5]helicenes is described. A central feature is the use of a sequential, non-reducing radical cyclisation reaction of (Z,Z)-1,4-bis(2-iodostyryl)benzene derivatives, viz. 3→1, mediated by tributyltin hydride.
