73311-70-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73311-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,1 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73311-70:
(7*7)+(6*3)+(5*3)+(4*1)+(3*1)+(2*7)+(1*0)=103
103 % 10 = 3
So 73311-70-3 is a valid CAS Registry Number.

Some uses of silicon compounds in organic synthesis

Fleming, Ian

, p. 7 - 13 (2007/10/02)

1.The amount of γ-phenylthioalkylation of silyl dienol ethers is increased when the triphenylsilyl ether is used in place of the trimethylsilyl ether.Phenylthiomethylation is the least γ-selective carbon electrophile of several tried so far. 2.The acid-catalysed reactions of a range of γ-silyl tertiary alcohols cleanly give rearrangement, in which the silyl group controls the outcome.The reactions are similar in several respects to the rearrangements of the corresponding pinacols, except that the silicon controlled reactions are usually cleaner and give higher yields.The reaction is particularly useful for setting up quaternary carbon atoms.
