Calculate Digit Verification of CAS Registry Number 682774-64:
(8*6)+(7*8)+(6*2)+(5*7)+(4*7)+(3*4)+(2*6)+(1*4)=207
207 % 10 = 7
So 682774-64-7 is a valid CAS Registry Number.

Vitamin D: A concise synthesis of the C19 hydroxylated enyne A-ring, an interesting precursor for the preparation of C19 substituted vitamin D analogues

Rodriguez, Rapha?l,Ollivier, Cyril,Santelli, Maurice

, p. 2289 - 2292 (2007/10/03)

A new C19 hydroxylated enyne 15, as potential A-ring building block of vitamin D analogues, was synthesized in enantiomerically pure form in nine steps from (-)-(S)-limonene. This short synthesis involved ozonolyzis of 1,2-limonene oxide followed by a Criegee rearrangement, epoxide trans diaxial ring opening by lithium acetylide, elimination, epoxidation and syn β-elimination of the resulting homopropargylic oxirane.
