Calculate Digit Verification of CAS Registry Number 77411-98:
(7*7)+(6*7)+(5*4)+(4*1)+(3*1)+(2*9)+(1*8)=144
144 % 10 = 4
So 77411-98-4 is a valid CAS Registry Number.

The Formation of Allyl Sulphides by Phenylthio-migration: Control by Silicon

Fleming, Ian,Paterson, Ian,Pearce, Andrew

, p. 256 - 262 (2007/10/02)

When γ-silyl-β-phenylthio-alcohols are treated with acid, the strategically placed silyl group encourages the rearrangement of the phenylthio-group, both from a secondary migration origin to a secondary migration terminus, and from a secondary migration origin to a tertiary migration terminus (4)->(6).Geraniol/nerol (12) and linalool (14) have been synthesised from a common intermediate (11) using this type of reaction.Phenylthio-migration from a tertiary migration origin (17)->(3) can be controlled to a limited extent by a suitably placed silyl group, but it is easier to achieve direct β-elimination of the silyl and phenylthio-groups (17)->(18).
