158497-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158497-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,4,9 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 158497-91:
(8*1)+(7*5)+(6*8)+(5*4)+(4*9)+(3*7)+(2*9)+(1*1)=187
187 % 10 = 7
So 158497-91-7 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
