Check Digit Verification of cas no

The CAS Registry Mumber 18981-63-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,8 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18981-63:
(7*1)+(6*8)+(5*9)+(4*8)+(3*1)+(2*6)+(1*3)=150
150 % 10 = 0
So 18981-63-0 is a valid CAS Registry Number.

Synthesis of L-daunosamine derivatives on the basis of the asymmetric dihydroxylation of 3-((E)-1-propenyl)-4,5-dihydroisoxazole

Wade, Peter A.,D'Ambrosio, Stephen G.,Rao, Jetla Appa,Shah-Patel, Sharmila,Cole, Damien T.,Murray Jr., James K.,Carroll, Patrick J.

, p. 3671 - 3677 (2007/10/03)

Methyl L-N,O-diacetyldaunosaminide was prepared from 3-nitro-4,5-dihydroisoxazole in 8.5% overall yield. A key step in the synthesis involved the AD reaction of (E)-3-(1-propenyl)-4,5-dihydroisoxazole (2b), affording the corresponding diol in 76% yield (92% ee). A second key step involved reductive cleavage of the dihydroisoxazole 4a and subsequent N-acetylation to afford separable diastereomeric γ-(acetylamino)alcohols 7a and 8a in 62% yield (72:28, 7a/8a). Swern oxidation of 7a and subsequent methanolysis followed by acetylation provided methyl L-N,O-diacetyldaunosaminide as an anomeric mixture. The AD reactions of chiral alkenyl dihydroisoxazole 16 with (DHQ)2-PHAL and (DHQD)2-PHAL afforded diastereomeric diol products, isolated as the acetates 18 and 19 (98:2 and 5:95 ratios, respectively, depending on the chiral auxiliary).

Acosamine and ristosamine derivatives were prepared via stereoselective reductive cleavage reactions of a benzylidenated dihydroisoxazolyl diol; the diol was prepared from 3-nitro-4,5-dihydroisoxazole via sequential propynylation, Lindlar reduction, and c
