Check Digit Verification of cas no

The CAS Registry Mumber 134599-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,9 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134599-99:
(8*1)+(7*3)+(6*4)+(5*5)+(4*9)+(3*9)+(2*9)+(1*9)=168
168 % 10 = 8
So 134599-99-8 is a valid CAS Registry Number.

Cascade synthesis of 2-pyridones using acrylamides and ketones

Rai, Sunil K.,Khanam, Shaziya,Khanna, Ranjana S.,Tewari, Ashish K.

, p. 44141 - 44145 (2014)

Microwave assisted non-catalytic condensation of 2-cyanoacetamide with aromatic aldehydes, and enolate mediated Michael-type addition to acrylamide followed by oxidative cyclization, produce 2-pyridones in good to excellent yield. Unsymmetrical ketones produce two regioisomeric enolates, therefore thermodynamic and kinetic products of butan-2-one and pentan-2-one have been isolated and fully characterized. This journal is
