208844-59-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 208844-59-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,8,4 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 208844-59:
(8*2)+(7*0)+(6*8)+(5*8)+(4*4)+(3*4)+(2*5)+(1*9)=151
151 % 10 = 1
So 208844-59-1 is a valid CAS Registry Number.

Silyl Route of Lactam Alkylation in Syntheses of Lactamodipeptide Amides
Shipov,Kramarova,Kalashnikova,Besova,Baukov
, p. 1736 - 1741 (2007/10/03)
A general route to lactamodipeptide amides is proposed, based on reaction of N-trimethylsilyl-lactams with ethoxycarbonylmethyl chloroacetate, followed by reaction of the resulting ethoxycarbonylmethyl esters of lactamoacetic acids with esters of amino ac
