721401-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 721401-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,1,4,0 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 721401-99:
(8*7)+(7*2)+(6*1)+(5*4)+(4*0)+(3*1)+(2*9)+(1*9)=126
126 % 10 = 6
So 721401-99-6 is a valid CAS Registry Number.

Total synthesis of octalactin A via ring-closing metathesis reaction
Buszek, Keith R,Sato, Nagaaki,Jeong, Youngmee
, p. 181 - 184 (2007/10/03)
A new total synthesis of the novel lactone natural product octalactin A is described. The key step involves the facile construction of the eight-membered lactone core via ring-closing metathesis (RCM). This oxocene was elaborated to give the powerful anti
