258348-49-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 258348-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,3,4 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 258348-49:
(8*2)+(7*5)+(6*8)+(5*3)+(4*4)+(3*8)+(2*4)+(1*9)=171
171 % 10 = 1
So 258348-49-1 is a valid CAS Registry Number.

Synthesis of methyl α-caryophylloside
Prandi, Jacques,Couturier, Gwéna?lle
, p. 49 - 52 (2007/10/03)
The convergent synthesis of caryophyllose, a new C-4 branched dodecose isolated from Pseudomonas caryophylli, is described from two monosaccharidic precursors. The key step is the diiodosamarium-promoted coupling of two six-carbon fragments: an acid chloride and a cyclic ketone.
