731772-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 731772-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,1,7,7 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 731772-78:
(8*7)+(7*3)+(6*1)+(5*7)+(4*7)+(3*2)+(2*7)+(1*8)=174
174 % 10 = 4
So 731772-78-4 is a valid CAS Registry Number.

Synthesis of functionalized 3-chloro-1-naphthols via Friedel-Crafts acylation of vinyl chlorides
Linghu, Xin,McLaughlin, Mark,Chen, Cheng-Yi,Reamer, Robert A.,Dimichele, Lisa,Davies, Ian W.
experimental part, p. 1550 - 1552 (2012/04/17)
Friedel-Crafts type cyclization of vinyl chlorides was developed into a general method for the synthesis of functionalized naphthols. The chloro functional group contained within these products allowed for further elaboration via cross-coupling reactions,
