906641-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 906641-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,6,6,4 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 906641-22:
(8*9)+(7*0)+(6*6)+(5*6)+(4*4)+(3*1)+(2*2)+(1*2)=163
163 % 10 = 3
So 906641-22-3 is a valid CAS Registry Number.

Synthesis of cyclophellitol utilizing a palladium chloride mediated-ferrier-II rearrangement
Takahashi, Hideyo,Ikegami, Shiro
, p. 901 - 911 (2007/10/03)
Cyclophellitol and its C3-epimer have been synthesized from 5-enoglucopyranoside and 5-enomannopyranoside, respectively. The carbocyclic skeleton was constructed through a Ferrier-II reaction meditated by PdCl 2.
