Calculate Digit Verification of CAS Registry Number 214853-58:
(8*2)+(7*1)+(6*4)+(5*8)+(4*5)+(3*3)+(2*5)+(1*8)=134
134 % 10 = 4
So 214853-58-4 is a valid CAS Registry Number.

Pinacol-type rearrangements of intramolecular photocycloadducts: Application of the 2,2-dimethyl-4-pentenoate protecting group

Crimmins, Michael T.,Carroll, Charlotte A.,Wells, Angela J.

, p. 7005 - 7008 (1998)

A pinacol-type rearrangement of intramolecular photocycloadducts has been accomplished by exploiting a novel ester protecting group that can be easilyremoved from a hindered alcohol. The ester is removed by an intramolecular lactonization, overcoming the steric factors normally associated with pivalate esters.
