880349-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 880349-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,0,3,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 880349-22:
(8*8)+(7*8)+(6*0)+(5*3)+(4*4)+(3*9)+(2*2)+(1*2)=184
184 % 10 = 4
So 880349-22-4 is a valid CAS Registry Number.

Progress toward the total synthesis of bielschowskysin: A stereoselective [2 + 2] photocycloaddition
Doroh, Brandon,Sulikowski, Gary A.
, p. 903 - 906 (2007/10/03)
The tetracyclic core of the diterpene bielschowskysin has been prepared as a single enantiomer via a stereoselective intramolecular [2 + 2] photocycloaddition of 5-alkylidene-2(5H)-furanone 3.
