1284237-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1284237-35-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,4,2,3 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1284237-35:
(9*1)+(8*2)+(7*8)+(6*4)+(5*2)+(4*3)+(3*7)+(2*3)+(1*5)=159
159 % 10 = 9
So 1284237-35-9 is a valid CAS Registry Number.

One-pot multistep synthesis of 3-aminoindolizine derivatives
Li, Lianhai,Chua, Waepril Kimberly S.
experimental part, p. 1392 - 1394 (2011/04/15)
We have developed an efficient one-pot multistep sequence to the synthesis of 3-aminoindolizine derivatives by using Hantzsch ester (9) as a mild hydride transfer agent. The reaction scope was investigated and the effect of substrates on reaction outcomes was discussed.
