478157-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 478157-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,1,5 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 478157-74:
(8*4)+(7*7)+(6*8)+(5*1)+(4*5)+(3*7)+(2*7)+(1*4)=193
193 % 10 = 3
So 478157-74-3 is a valid CAS Registry Number.

A 6-exo-trig radical cyclization approach to the hydrochrysene skeleton
Zhang, Xuqing,Guzi, Timothy,Pettus, Liping,Schultz, Arthur G
, p. 7605 - 7608 (2007/10/03)
The synthetic approach to a functionalized hydrochrysene skeleton is described. The route is highlighted by a Birch reduction-alkylation sequence and a 6-exo-trig radical cyclization.
