214335-71-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 214335-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,3,3 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 214335-71:
(8*2)+(7*1)+(6*4)+(5*3)+(4*3)+(3*5)+(2*7)+(1*1)=104
104 % 10 = 4
So 214335-71-4 is a valid CAS Registry Number.

Total synthesis of naturally configured pyrrhoxanthin, a carotenoid butenolide from plankton

Burghart, Johen,Brueckner, Reinhard

scheme or table, p. 7664 - 7668 (2009/04/11)

A carotenoid from the chemical kitchen: Two sequential Stille couplings of an unsymmetric distannane building block with a bromoolefin and a bromoalkyne terminated a highly convergent synthesis of the title compound, pyrrhoxanthin (see scheme).
