Check Digit Verification of cas no
The CAS Registry Mumber 288069-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,0,6 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 288069-43:
(8*2)+(7*8)+(6*8)+(5*0)+(4*6)+(3*9)+(2*4)+(1*3)=182
182 % 10 = 2
So 288069-43-2 is a valid CAS Registry Number.

Synthesis of 3,5-O-benzylidene-2-deoxy-L-riboaldose from 5,5-dihydroxy- 2-phenyl-1,3-dioxane
Ulven, Trond,Carlsen, Per H. J.
, p. 2275 - 2280 (2000)
The asymmetric alkylation of 2-phenyl-1,3-dioxan-5-one was achieved via the RAMP-hydrazone. Regeneration of the ketone followed by stereoselective reduction and ozonolysis, gave the protected 2-deoxy-L-ribose, 3,5-O- benzyldiene-2-deoxy-L-erythro-pentoald
