176238-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176238-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,2,3 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 176238-53:
(8*1)+(7*7)+(6*6)+(5*2)+(4*3)+(3*8)+(2*5)+(1*3)=152
152 % 10 = 2
So 176238-53-2 is a valid CAS Registry Number.

Synthesis of 3-acetyl-2-amino-4-pyridone
Dorokhov,Komkov,Sakharov,Bogdanov
, p. 168 - 170 (2007/10/03)
A method for synthesizing 3-acetyl-2-amino-4-pyridone has been suggested. The synthesis involves the condensation of dimethylformamide dimethylacetal at the NH2 group of diphenylboron chelate diacetylketene aminal followed by its intramolecular cyclization under the action of NaOMe in MeOH.
