Check Digit Verification of cas no

The CAS Registry Mumber 102313-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,3,1 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 102313-71:
(8*1)+(7*0)+(6*2)+(5*3)+(4*1)+(3*3)+(2*7)+(1*1)=63
63 % 10 = 3
So 102313-71-3 is a valid CAS Registry Number.

, p. 1715 - 1717 (1998)

1-Alkyl-5-(alkylaminocarbonyl)-4,6-dimethyl-2-pyridones were obtained in high yields from the self-condensation of N-alkyl-3-oxobutanamides in the presence of p-toluenesulfonic acid as a catalyst at 100-110°C for 11-24 hours without solvent.

Approach to polysubstituted 4-pyridones from N-Aryl acetoacetamides via a N to C 1,3-acyl migration mediated by sodium persulfate

Zhang, Zhiguo,Fang, Shiliang,Liu, Qingfeng,Zhang, Guisheng

supporting information, p. 7665 - 7670 (2012/10/30)

Mediated by sodium persulfate (Na2S2O8), a series of polysubstituted 4-pyridones were synthesized via self-condensation of N-aryl acetoacetamides, during which a novel N to C 1,3-acyl migration should be involved. The stru
