142836-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142836-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,3 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142836-55:
(8*1)+(7*4)+(6*2)+(5*8)+(4*3)+(3*6)+(2*5)+(1*5)=133
133 % 10 = 3
So 142836-55-3 is a valid CAS Registry Number.

Simple Synthesis of Furanoid and Dioxabicyclooctane Lignans
Mitra, Jayati,Mitra, Alok K.
, p. 1285 - 1286 (2007/10/02)
The key intermediates, the keto lactones 5, 6 obtained by convergent synthesis, were transformed into furanoid and dioxabicyclooctane lignan analogues 7, 8 by means of sodium borohydride reduction and subsequent acid-catalysed cyclisation.
