650625-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 650625-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,0,6,2 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 650625-31:
(8*6)+(7*5)+(6*0)+(5*6)+(4*2)+(3*5)+(2*3)+(1*1)=143
143 % 10 = 3
So 650625-31-3 is a valid CAS Registry Number.

An unexpected formation of a 14-membered cyclodepsipeptide
Iliev, Boyan,Linden, Anthony,Heimgartner, Heinz
, p. 3215 - 3234 (2007/10/03)
The treatment of diluted solutions of the hydroxy diamides 6a and 6b in toluene with HCl gas at 100° gave the dimeric, 14-membered cyclodepsipeptide 10 in up to 72% yield (Scheme 3). The same product was formed from the linear dimer of 6b, the depsipeptid
