674335-99-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 674335-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,4,3,3 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 674335-99:
(8*6)+(7*7)+(6*4)+(5*3)+(4*3)+(3*5)+(2*9)+(1*9)=190
190 % 10 = 0
So 674335-99-0 is a valid CAS Registry Number.

Total Synthesis of (-)-Apicularen A
Su, Qibin,Panek, James S.
, p. 2425 - 2430 (2007/10/03)
Complete details of an asymmetric synthesis of apicularen (1) are described. The synthesis has been accomplished using a highly diastereo- and enantioselective [4 + 2] annulation for the assembly of the functionalized pyran core. An underdeveloped lactoni
