1020203-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1020203-68-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,2,0 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1020203-68:
(9*1)+(8*0)+(7*2)+(6*0)+(5*2)+(4*0)+(3*3)+(2*6)+(1*8)=62
62 % 10 = 2
So 1020203-68-2 is a valid CAS Registry Number.

Naito, Hiroyuki,Hata, Takeshi,Urabe, Hirokazu
, p. 2298 - 2301 (2008/09/18)
Stereoselective preparation of unsymmetrically protected 2-alkylidene-1,3-imidazolidines was achieved by the reaction of N,N′-protected ethylenediamine, bromopropynamide, and K3PO4 in hot DMF. When N-protected aminoethanol was used i
