74947-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74947-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,4 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74947-65:
(7*7)+(6*4)+(5*9)+(4*4)+(3*7)+(2*6)+(1*5)=172
172 % 10 = 2

Ward, Frederick E.,Buckler, Robert T.
, p. 4608 - 4611 (2007/10/02)
Phosgene, in the presence of 2,6-lutidine, reacts with alkyl esters of 3-amino-2-benzoylcrotonic acid to give as major products 1,3-oxazin-2-ones, formally derived from the reaction of 2 equiv of amino ester with 2 and 3 equiv of phosgene.Ethyl 3-amino-2-
