Check Digit Verification of cas no

The CAS Registry Mumber 845512-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,5,1 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 845512-99:
(8*8)+(7*4)+(6*5)+(5*5)+(4*1)+(3*2)+(2*9)+(1*9)=184
184 % 10 = 4
So 845512-99-4 is a valid CAS Registry Number.

Total synthesis of gambierol: Subunit coupling and completion

Johnson, Henry W. B.,Majumder, Utpal,Rainier, Jon D.

, p. 1747 - 1753 (2008/02/02)

The preceding manuscript detailed our synthesis of the gambierol A-C and F-H ring precursors. Reported herein is a description of the coupling of the two precursors and the conversion of the coupled material into gambierol. Coupling of the subunits involv

The total synthesis of gambierol

Johnson, Henry W. B.,Majumder, Utpal,Rainier, Jon D.

, p. 848 - 849 (2007/10/03)

This communication describes the total synthesis of the marine polyether toxin, gambierol. This work couples our iterative C-glycoside/enol ether-olefin metathesis strategy to the subunits with a unique olefin metathesis/carbonyl olefination reaction to bring the subunits together. Copyright
