909009-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909009-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,0,0 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 909009-72:
(8*9)+(7*0)+(6*9)+(5*0)+(4*0)+(3*9)+(2*7)+(1*2)=169
169 % 10 = 9
So 909009-72-9 is a valid CAS Registry Number.

A novel synthesis of β-lactam fused cyclic enediynes by intramolecular Kinugasa reaction
Pal, Runa,Basak, Amit
, p. 2992 - 2994 (2008/09/19)
A general synthetic route to β-lactam-fused enediynes by intramolecular Kinugasa reaction has been successfully developed. The method has widened the scope of Kinugasa reaction in the synthesis of sensitive systems like the one described in this communica
