862503-05-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 862503-05-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,5,0 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 862503-05:
(8*8)+(7*6)+(6*2)+(5*5)+(4*0)+(3*3)+(2*0)+(1*5)=157
157 % 10 = 7
So 862503-05-7 is a valid CAS Registry Number.

Three-step synthesis of sialic acids and derivatives

Hong, Zhangyong,Liu, Lei,Hsu, Che-Chang,Wong, Chi-Huey

, p. 7417 - 7421 (2006)

(Chemical Equation Presented) Flexible yet efficient: Sialic acids such as L-N-acetylneuraminic acid (see picture) can be synthesized in only three steps by 1) vinylation of an aldose through a modified Petasis coupling reaction, 2) 1,3-dipolar cycloaddition with a nitrone to construct an isoxazolidine ring, and 3) base-catalyzed β elimination/ring opening of the isoxazolidine to generate a γ-hydroxy-α-keto acid.
