Check Digit Verification of cas no

The CAS Registry Mumber 1446357-60-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,6,3,5 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1446357-60:
(9*1)+(8*4)+(7*4)+(6*6)+(5*3)+(4*5)+(3*7)+(2*6)+(1*0)=173
173 % 10 = 3
So 1446357-60-3 is a valid CAS Registry Number.

Expeditive access to 2-substituted 4 h -pyrido[1,3]oxazin-4-ones via an intramolecular O-arylation

supporting information, p. 3494 - 3497 (2013/08/15)

Unreported 2-substituted 4H-pyrido[e][1,3]oxazin-4-ones are synthesized via an unprecedented intramolecular O-arylation of N-aroyl- and N-heteroaroyl-(iso)nicotinamides under microwave irradiations, in good to excellent yields. The broad applicability was demonstrated by 24 examples with a variety of substituents at the 2-position of the final compounds and 3 possible positions for the nitrogen atom of the pyridine ring. In addition, transformation of one of these compounds into 2-hydroxypyridyl-substituted 1,2,4-triazole and 1,2,4-oxazinone was realized. This approach opens a rapid access to a new bicyclic heteroaromatic chemical series with high potential in medicinal chemistry.
