220509-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220509-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,0 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220509-18:
(8*2)+(7*2)+(6*0)+(5*5)+(4*0)+(3*9)+(2*1)+(1*8)=92
92 % 10 = 2
So 220509-18-2 is a valid CAS Registry Number.

Kogoshi, Naoto,Takatsuki, Akira,Kim, Yong Jip,Kitahara, Takeshi
, p. 63 - 66 (2007/10/03)
ent-Nectrisine (2), the unnatural enantiomer of nectrisine (1), a potent α-glucosidase inhibitor, was synthesized from D-glucose derivative. Biological assay showed that 2 had no significant bioactivity.
