Check Digit Verification of cas no

The CAS Registry Mumber 129217-11-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,1 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129217-11:
(8*1)+(7*2)+(6*9)+(5*2)+(4*1)+(3*7)+(2*1)+(1*1)=114
114 % 10 = 4
So 129217-11-4 is a valid CAS Registry Number.

A facile one-pot solid-phase synthesis of oxazolidin-2-ones using polymer-supported 2-hydroxyalkyl selenide reagent

Hu, Qiao-Sheng,Sheng, Shou-Ri,Lin, Shu-Ying,Wei, Mei-Hong,Xin, Qin,Liu, Xiao-Ling

, p. 74 - 75 (2008/02/04)

A simple, efficient and environmentally friendly procedure for one-pot solid-phase synthesis of 2-oxazolidinones in moderate to good yields by reaction of polystyrene-supported 2-hydroxyalkyl selenide with benzoyl isocyanate and subsequent oxidation/cycli

Formation of N-Tributylstannyl Heterocycle from Bis(tributyltin) Oxide and ω-Haloalkyl Isocyanate. One-Pot Convenient Synthesis of 2-Oxazolidinones and Tetrahydro-2H-1,3-oxazin-2-one

Shibata, Ikuya,Nakamura, Kenji,Baba, Akio,Matsuda, Haruo

, p. 853 - 859 (2007/10/02)

Novel types of compounds, N-tributylstannyl-2-oxazolidinone (4a) and tetrahydro-2H-1,3-oxazin-2-one (4b), are formed from the adduct of (n-Bu3Sn)2O (1) with ω-haloalkyl isocyanate (2), and the subsequent coupling reaction with alkyl halides gives a variety of N-substituted 2-oxazolidinones and tetrahydro-2-oxazinones in a one-pot procedure.Both the cyclization and the coupling reaction proceed quantitatively in the presence of HMPA which enhances the reactivity of the Sn-heteroatom bond by coordination.
