Check Digit Verification of cas no

The CAS Registry Mumber 1429867-71-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,9,8,6 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1429867-71:
(9*1)+(8*4)+(7*2)+(6*9)+(5*8)+(4*6)+(3*7)+(2*7)+(1*1)=209
209 % 10 = 9
So 1429867-71-9 is a valid CAS Registry Number.

Multicomponent assembly of diverse pyrazin-2(1 H)-one chemotypes

Azuaje, Jhonny,El Maatougui, Abdelaziz,Perez-Rubio, Jose M.,Coelho, Alberto,Fernandez, Franco,Sotelo, Eddy

, p. 4402 - 4409 (2013/06/05)

An expedient and concise Ugi-based approach for the rapid assembly of pyrazin-2(1H)-one-based frameworks has been developed. This convergent approach encompasses skeletal, functional and stereochemical diversity, exhibiting an unusually high bond-forming efficiency as well as high structure and step economies. The method involves the use of readily available commercial reagents and is an example of the reconciliation of structural complexity with operational simplicity in a time- and cost-effective manner.
