944994-64-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 944994-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,9,9 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 944994-64:
(8*9)+(7*4)+(6*4)+(5*9)+(4*9)+(3*4)+(2*6)+(1*4)=233
233 % 10 = 3
So 944994-64-3 is a valid CAS Registry Number.

Studies toward the synthesis of phomactin A. An approach to the macrocyclic core
Teng, Dawei,Wang, Bo,Augatis, Alex J.,Totah, Nancy I.
, p. 4605 - 4607 (2007)
An approach to the macrocyclic core of phomactin A is described. Central to this strategy is the use of a cis-fused oxadecalin intermediate, prepared using the dihydropyrone Diels-Alder reaction. The conformational bias inherent to this system is then use
