194468-85-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 194468-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,4,6 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 194468-85:
(8*1)+(7*9)+(6*4)+(5*4)+(4*6)+(3*8)+(2*8)+(1*5)=184
184 % 10 = 4
So 194468-85-4 is a valid CAS Registry Number.

Use of Winterfeldt's template to control the C-2' configuration in the synthesis of strigol-type compounds

Roehrig, Susanne,Hennig, Lothar,Findeisen, Matthias,Welzel, Peter,Mueller, Dietrich

, p. 3439 - 3456 (1998)

A route comprising (i) a cycloaddition reaction of citraconic anhydride with the Winterfeldt auxiliary, (ii) hydride reduction of the cycloadduct, (iii) a (formal) ether formation, and (iv) a cycloreversion reaction allows efficient stereocontrol at C-2' in the synthesis of strigol and its structural analogues.
