330855-79-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 330855-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,8,5 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 330855-79:
(8*3)+(7*3)+(6*0)+(5*8)+(4*5)+(3*5)+(2*7)+(1*9)=143
143 % 10 = 3
So 330855-79-3 is a valid CAS Registry Number.

Soliman,Khodairy,Ahmed
, p. 649 - 665 (2007/10/03)
The reaction of N-chloroacetyl derivatives 6-10 with morpholine yielded N-morpholin-1-yl acetyl derivatives 11-15, which were subjected to Thorpe-Zieler cyclization with sodium tert-butoxide to produce the corresponding condensed pyridin-2(1H)-one derivat
