Check Digit Verification of cas no

The CAS Registry Mumber 35998-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,9,9 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 35998-80:
(7*3)+(6*5)+(5*9)+(4*9)+(3*8)+(2*8)+(1*0)=172
172 % 10 = 2
So 35998-80-2 is a valid CAS Registry Number.

Metal-free approach for the ?-proline mediated synthesis of nitrones from nitrosobenzene

Choi, Minho,Viji, Mayavan,Kim, Donghwan,Lee, Young Hee,Sim, Jaeuk,Kwak, Young-Shin,Lee, Kiho,Lee, Heesoon,Jung, Jae-Kyung

, p. 4182 - 4187 (2018)

An efficient, and metal-free approach for the ?-proline mediated synthesis of nitrones from nitrosobenzene and benzaldehydes has been established. The reaction undergoes very efficiently at room temperature in methanol as a solvent. The reaction is assumed to involve that the initial formation of azomethine ylide and [2 + 3] cycloaddition of nitrosobenzene, followed by the subsequent retro [2 + 3] cycloaddition could offer the desired nitrone.
