Check Digit Verification of cas no

The CAS Registry Mumber 1417888-44-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,8,8 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1417888-44:
(9*1)+(8*4)+(7*1)+(6*7)+(5*8)+(4*8)+(3*8)+(2*4)+(1*4)=198
198 % 10 = 8
So 1417888-44-8 is a valid CAS Registry Number.

A versatile method for the synthesis of heterocyclic ring-fused 1,2-oxazinones from the NHC-catalyzed reactions of 2-aroylvinylarylaldehydes with nitrosoarenes

Qu, Jing,Cheng, Ying

, p. 888 - 894 (2013/07/25)

The NHC-catalyzed reactions of nitrosoarenes with 4-(2-aroylvinyl)furan-3- carbaldehydes, 4-(2-aroylvinyl) thiophene-3-carbaldehydes or 2-(2-aroylvinyl)nicotinaldehydes were studied, which produced novel furo [3,4-d][1,2]oxazin-4-ones, thieno[3,4-d][1,2]oxazin-4-ones or pyrido[3,2-d][1,2]oxazin-5-ones, respectively. This work developed a versatile method for the construction of different types of heterocyclic ringfused 1,2-oxazinones that are not easy accessible by other methods.
