134852-87-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 134852-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,5 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134852-87:
(8*1)+(7*3)+(6*4)+(5*8)+(4*5)+(3*2)+(2*8)+(1*7)=142
142 % 10 = 2
So 134852-87-2 is a valid CAS Registry Number.

AN ENANTIOSELECTIVE TOTAL SYNTHESIS OF THE MACRODIOLIDE (-)-(RRR)-COLLETALLOL

Dommerholt, F. J.,Thijs, L.,Zwanenburg, B.

, p. 1495 - 1498 (1991)

The total synthesis of (-)-colletallol, a naturally occurring macrodiolide, has been completed in 26 steps.An essential step in the sequence is the photo-induced rearrangement of an α,β-epoxy diazomethyl ketone to produce a 4-hydroxy-2-alkenoate.

Total synthesis of the macrodiolide pyrenophorol

Dommerholt,Thijs,Zwanenburg

, p. 1499 - 1502 (2007/10/02)

By means of a total synthesis, the absolute configuration of the naturally occurring macrodiolide pyrenophorol has been established. An essential step is the photo-induced rearrangement of an α,β-epoxy diazomethyl ketone to produce a 4-hydroxy-2-alkenoate. The two lactone units have been introduced in two successive steps.
