Check Digit Verification of cas no
The CAS Registry Mumber 11031-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,0,3 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 11031-47:
(7*1)+(6*1)+(5*0)+(4*3)+(3*1)+(2*4)+(1*7)=43
43 % 10 = 3
So 11031-47-3 is a valid CAS Registry Number.

The synthesis of sarcinaxanthin ((2R,6R,2'R,6'R)-1), a symmetrical C50-carotenoid with two γ-end groups, isolated from Sarcina lutea and from Cellulomonas biazotea as major pigment, was based on the strategy C20 + C10 + C
SYNTHESIS OF BACTERIAL C50 CAROTENOID SARCINAXANTHIN.

Alkylation of the distal double bond of geranyl acetate 8 with isoprene epoxide 5 has been carried out under anhydrous ZnCl2/nitromethane conditions to give a mixture of C15 hydroxyprenylated compounds.The major diol acetate isomer 12 was dehydrated to the expected γ-cis synthon 17 which was converted into racemic sarcinaxanthin 3 in few steps through the corresponding sulfone 21.
