Check Digit Verification of cas no
The CAS Registry Mumber 463-98-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 463-98:
(5*4)+(4*6)+(3*3)+(2*9)+(1*8)=79
79 % 10 = 9
So 463-98-9 is a valid CAS Registry Number.

Rapid, one-pot synthesis of β-siloxy-α-haloaldehydes
Saadi, Jakub,Akakura, Matsujiro,Yamamoto, Hisashi
, p. 14248 - 14251 (2011)
The Mukaiyama cross-aldol reaction of α-fluoro-, α-chloro-, and α-bromoacetaldehyde-derived (Z)-tris(trimethylsilyl)silyl enol ethers is described, furnishing anti-β-siloxy-α-haloaldehydes. A highly diastereoselective, one-pot, sequential double-aldol process is developed, affording novel β,δ-bissiloxy-α,γ-bishaloaldehydes. Reactions are catalyzed by C6F5CHTf2 and C 6F5CTf2AlMe2 (0.5-1.5 mol %) and provide access to halogenated polyketide fragments.
